A complex with nitrogen single, double, and triple bonds to the same chromium atom: synthesis, structure, and reactivity.

ABSTRACT: A nitrogen-based analogue of the Schrock and Clark "yl-ene-yne" complex, W(CBu ^t )(CHBu ^t )(CH₂Bu ^t )(dmpe), has been prepared. The new complex is the nitrido, imido, amido anion [NCr(NPh)(NPrⁱ₂)₂]^-, which was structurally characterized with the [K(crypt-2.2.2)]⁺ counterion. The "Cr-N 1-2-3" complex was prepared from NCr(NHPh)(NPrⁱ₂)₂, which exists as this nitrido-amido tautomer, rather than the bis(imido) Cr(NH)(NPh)(NPrⁱ₂)₂. By selection of electrophile, the nitrido-imido salt K[NCr(NPh)(NPrⁱ₂)₂] can undergo reaction at either the imido or the nitrido to form unusual examples of nitrido or bis(imido) complexes.

Enzymatic activation of the nitrogen atom in peptide bonds

Project description:Abstract The peptide bond is the defining feature of proteins, it co ntrols their structure by enforcing planarity and governs their chemistry by abolishing nucleophili city. This behaviour results from the delocalisation of the lone pair of electrons on the nitrogen atom into the adjacent carbonyl bond. Methylating an amide bond by conventional chemistry usually requires a metal to generate the amide anion. The OphA enzyme methyla tes amide bonds at pH 7 in water using S-adenosyl methionine (SAM) as co-factor. The st ructure of OphA reveals a complex catenane arrangement in which the substrate i s clamped adjacent to SAM. Site directed mutants have identified the key catalytic residue s. A mechanism in which conjugation of the peptide bond is disrupted by van der Waals in teractions between SAM and the amide nitrogen is proposed and tested. The methylation of amides is of particular interest as it greatly enhances the cell permeability of peptides.

Nucleophilic reactivity of the gold atom in a diarylborylgold(i) complex toward polar multiple bonds.

Project description:A di(o-tolyl)borylgold complex was synthesized via the metathesis reaction of a gold alkoxide with tetra(o-tolyl)diborane(4). The resulting diarylborylgold complex exhibited a Lewis acidic boron center and a characteristic visible absorption that arises from its HOMO-LUMO excitation, which is narrower than that of a previously reported dioxyborylgold complex. The diarylborylgold complex reacted with isocyanide in a stepwise fashion to afford single- and double-insertion products and a C-C coupled product. Reactions of this diarylborylgold complex with C[double bond, length as m-dash]O/N double bond species furnished addition products under concomitant formation of Au-C and B-O/N bonds, which suggests nucleophilic reactivity of the gold metal center. DFT calculations provided details of the underlying reaction mechanism, which involves an initial coordination of the C[double bond, length as m-dash]O/N bond to the boron vacant p-orbital of the diarylboryl ligand followed by a migration of the gold atom from the tetracoordinate sp3-hybridized boron center, which is analogous to the reactivity of the conventional sp3-hybridized borate species. The DFT calculations also suggested a stepwise mechanism for the reaction of this diarylborylgold complex with isocyanide, which afforded three different reaction products depending on the applied reaction conditions.

Chromium(IV)-peroxo complex formation and its nitric oxide dioxygenase reactivity.

Project description:The O(2) and NO reactivity of a Cr(II) complex bearing a 12-membered tetraazamacrocyclic N-tetramethylated cyclam (TMC) ligand, [Cr(II)(12-TMC)(Cl)](+) (1), and the NO reactivity of its peroxo derivative, [Cr(IV)(12-TMC)(O(2))(Cl)](+) (2), are described. By contrast to the previously reported Cr(III)-superoxo complex, [Cr(III)(14-TMC)(O(2))(Cl)](+), the Cr(IV)-peroxo complex 2 is formed in the reaction of 1 and O(2). Full spectroscopic and X-ray analysis revealed that 2 possesses side-on ?(2)-peroxo ligation. The quantitative reaction of 2 with NO affords a reduction in Cr oxidation state, producing a Cr(III)-nitrato complex, [Cr(III)(12-TMC)(NO(3))(Cl)](+) (3). The latter is suggested to form via a Cr(III)-peroxynitrite intermediate. [Cr(II)(12-TMC)(NO)(Cl)](+) (4), a Cr(II)-nitrosyl complex derived from 1 and NO, could also be synthesized; however, it does not react with O(2).

An atom-economic synthesis of nitrogen heterocycles from alkynes.

Project description:A robust route to 2,4-disubstituted pyrrole heterocycles relying upon a cascade reaction is reported. The reaction benefits from operational simplicity: it is air and moisture tolerant and is performed at ambient temperature. Control over the reaction conditions provides ready access to isopyrroles, 2,3,4-trisubstituted pyrroles, and 3-substituted pyrollidin-2-ones.

A Nonheme Thiolate-Ligated Cobalt Superoxo Complex: Synthesis and Spectroscopic Characterization, Computational Studies, and Hydrogen Atom Abstraction Reactivity.

Project description:The synthesis and characterization of a Co(II) dithiolato complex Co(Me3TACN)(S2SiMe2) (1) are reported. Reaction of 1 with O2 generates a rare thiolate-ligated cobalt-superoxo species Co(O2)(Me3TACN)(S2SiMe2) (2) that was characterized spectroscopically and structurally by resonance Raman, EPR, and X-ray absorption spectroscopies as well as density functional theory. Metal-superoxo species are proposed to S-oxygenate metal-bound thiolate donors in nonheme thiol dioxygenases, but 2 does not lead to S-oxygenation of the intramolecular thiolate donors and does not react with exogenous sulfur donors. However, complex 2 is capable of oxidizing the O-H bonds of 2,2,6,6-tetramethylpiperidin-1-ol derivatives via H atom abstraction. Complementary proton-coupled electron-transfer reactivity is seen for 2 with separated proton/reductant pairs. The reactivity studies indicate that 2 can abstract H atoms from weak X-H bonds with bond dissociation free energy (BDFE) ≤ 70 kcal mol-1. DFT calculations predict that the putative Co(OOH) product has an O-H BDFE = 67 kcal mol-1, which matches the observed pattern of reactivity seen for 2. These data provide new information regarding the selectivity of S-oxygenation versus H atom abstraction in thiolate-ligated nonheme metalloenzymes that react with O2.

The hydrogen atom transfer reactivity of a porphyrinoid cobalt superoxide complex.

Project description:The H-atom transfer (HAT) reactivity of a corrolazine cobalt superoxide with weak O-H and N-H substrates has been demonstrated. Kinetic analysis shows relatively fast rates of HAT with diphenylhydrazine (DPH). A kinetic isotope effect (KIE) and Eyring activation parameters are consistent with an HAT mechanism.

Closed Shell Iron(IV) Oxo Complex with an Fe-O Triple Bond: Computational Design, Synthesis, and Reactivity.

Project description:Iron(IV)-oxo intermediates in nature contain two unpaired electrons in the Fe-O antibonding orbitals, which are thought to contribute to their high reactivity. To challenge this hypothesis, we designed and synthesized closed-shell singlet iron(IV) oxo complex [(quinisox)Fe(O)]+ (1+ ; quinisox-H=(N-(2-(2-isoxazoline-3-yl)phenyl)quinoline-8-carboxamide). We identified the quinisox ligand by DFT computational screening out of over 450?candidates. After the ligand synthesis, we detected 1+ in the gas phase and confirmed its spin state by visible and infrared photodissociation spectroscopy (IRPD). The Fe-O stretching frequency in 1+ is 960.5?cm-1 , consistent with an Fe-O triple bond, which was also confirmed by multireference calculations. The unprecedented bond strength is accompanied by high gas-phase reactivity of 1+ in oxygen atom transfer (OAT) and in proton-coupled electron transfer reactions. This challenges the current view of the spin-state driven reactivity of the Fe-O complexes.

Mild synthesis of diboryldiborenes by diboration of B-B triple bonds.

Project description:A set of diboryldiborenes are prepared by the mild, catalyst-free, room-temperature diboration of the B-B triple bonds of doubly base-stabilized diborynes. Two of the product diboryldiborenes are found to be air- and water-stable in the solid state, an effect that is attributed to their high crystallinity and extreme insolubility in a wide range of solvents.

Reduction of organic azides by indyl-anions. Isolation and reactivity studies of indium-nitrogen multiple bonds.

Project description:The synthesis of a new potassium-indyl complex, K[In(NONAr)] (NONAr = [O(SiMe2NAr)2]2-, Ar = 2,6-iPr2C6H3) and its reactivity with organic azides RN3 is reported. When R = 2,6-bis(diphenylmethyl)-4- t Bu-phenyl, a dianionic alkyl-amide ligand is formed via C-H activation across a transient In-Nimide bond. Reducing the size of the R-group to 2,4,6-trimethylphenyl (mesityl, Mes) enables oxidation of the indium and elimination of dinitrogen to afford the imide species, K[In(NONAr)(NMes)]. The anion contains a short In-Nimide bond, shown computationally to contain appreciable multiple bond character. Reaction of isolated imides with an additional equivalent of azide (R = Mes, SiMe3) generates tetrazenido-indium compounds K[In(NONAr){κ-N,N'-N4(Mes)(R)-1,4}], shown by X-ray crystallography to contain planar InN4 heterocycles in the anion.

Chromium-catechin complex, synthesis and toxicity check using bacterial models.

Project description:Chromium-catechin complex was synthesized by reacting [Cr(H2O)6]2+ (hexa-aqua) with catechin as a ligand. Toxicity studies were carried out for the complex using bacterial models for safer application of this complex in the future as a drug. Chromium-catechin complex was characterized using ESI Mass spectrometry, electronic spectroscopy, FT-IR spectroscopy and cyclic voltammetry. The complex was found mildly inhibitory towards B. subtilis with the mode of action being oxidative damage, targeting cell membrane. The complex was supportive towards E. coli, which was evident from the growth profile and inhibition studies. SEM analysis supported the results of membrane integrity studies, where the bacterial liposomes upon treatment with the complex revealed slight morphological changes in the case of B. subtilis, without any change in the case of E. coli. The toxicity studies on chromium-catechin complex using bacterial model saves time, as well as resources by providing quick and reliable results, which could ease up the work to be done in future with higher group of organisms like animal model. Therefore, in the future, this complex can be used as an antidiabetic drug after performing toxicity studies with animal model.
