Electron transfer-induced coupling of haloarenes to styrenes and 1,1-diphenylethenes triggered by diketopiperazines and Potassium tert-butoxide.

ABSTRACT: The coupling of haloarenes to styrenes and 1,1-diarylethenes has been achieved with potassium tert-butoxide in the presence of N,N'-dialkyldiketopiperazines. In contrast to previously reported reactions where phenanthroline has been used to mediate the reactions, the use of diketopiperazines can lead to either 1,1,2-triarylethenes or 1,1,2-triarylethanes, depending on the conditions used.

Mechanistic insights into the potassium tert-butoxide-mediated synthesis of N-heterobiaryls.

Project description:We report herein that symmetrical and non-symmetrical N-heterobiaryls are produced by a potassium tert-butoxide-mediated dimerization of heterocyclic N-oxides. The reaction is scalable and transition metal-free, and can be carried out under thermal and microwave conditions. Preliminary mechanistic studies point to the involvement of radical anionic intermediates arising from the N-oxide substrates and potassium tert-butoxide.

Synthesis of zirconium(IV) and hafnium(IV) isopropoxide, <i>sec</i>-butoxide and <i>tert</i>-butoxide.

Project description:We revisited the synthesis of zirconium(IV) and hafnium(IV) alkoxides, namely the metal isopropoxide isopropanol complex (M(OiPr)4·iPrOH, M = Zr, Hf) and the metal sec- and tert-butoxide (M(OsBu)4 and M(OtBu)4, M = Zr, Hf). We optimized the most convenient synthesis methods and compared the products with commercial sources. En route to the metal sec- and tert-butoxides, we synthesized the metal diethylamido complex (M(NEt2)4, M = Zr, Hf).

Synthesis of 2-Aryl- and 2-Vinylpyrrolidines via Copper-Catalyzed Coupling of Styrenes and Dienes with Potassium β-Aminoethyl Trifluoroborates.

Project description:2-Arylpyrrolidines occur frequently in bioactive compounds, and thus, methods to access them from readily available reagents are valuable. We report a copper-catalyzed intermolecular carboamination of vinylarenes with potassium N-carbamoyl-β-aminoethyltrifluoroborates. The reaction occurs with terminal, 1,2-disubstituted, and 1,1-disubstituted vinylarenes bearing a number of functional groups. 1,3-Dienes are also good substrates, and their reactions give 2-vinylpyrrolidines. Radical clock mechanistic experiments are consistent with the presence of carbon radical intermediates and do not support participation of carbocations.

1,1'-Di-tert-butyl-2,2',3,3',4,4',5,5'-octa-ethyl-1,1'-bis-tannole.

Project description:The title compound, [Sn(2)(C(4)H(9))(2)(C(12)H(20))(2)], has two 1-stannacyclo-penta-diene skeletons related by inversion symmetry located at the mid-point of the Sn-Sn bond [2.7682 (2) Å]. Thus, the asymmetric unit comprises one half-mol-ecule. The planarity of the stannacyclo-penta-diene ring is illustrated by the dihedral angle of 0.3 (1)°, defined by the C(4) and C-Sn-C planes. To avoid steric repulsion, the two stannole rings are oriented in an anti fashion through the Sn-Sn bond. These structural features are similar to those of other bis-tannoles.

1,1'-Bis(tert-butyl-dimethyl-sil-yl)ferrocene.

Project description:The asymmetric unit of the title compound, [Fe(C11H19Si)2], consists of one half of a ferrocene derivative. The Fe(II) atom lies on a twofold rotation axis, giving an eclipsed conformation for the cyclo-penta-dienyl ligands. No significant inter-molecular inter-actions are observed in the crystal structure.

(R)-Di-tert-butyl 1,1'-binaphthyl-2,2'-dicarboxyl-ate.

Project description:The crystal structure of the title compound, C(30)H(30)O(4), comprises two crystallographically independent half-mol-ecules which are completed by crystallographic twofold symmetry. The dihedral angles between the naphthalene ring planes are 85.83?(3) and 83.69?(3)° for the two molecules. The atoms of the tert-butyl group of one mol-ecule are disordered over two sets of sites with occupancies of 0.60:0.40. The crystal packing is achieved via ?-? stacking inter-actions between the naphthyl groups of adjacent mol-ecules, with a separation of 3.790?(1)?Å between the centroids of the rings.

Strong signature of electron-vibration coupling in molecules on Ag(111) triggered by tip-gated discharging.

Project description:Electron-vibration coupling is of critical importance for the development of molecular electronics, spintronics, and quantum technologies, as it affects transport properties and spin dynamics. The control over charge-state transitions and subsequent molecular vibrations using scanning tunneling microscopy typically requires the use of a decoupling layer. Here we show the vibronic excitations of tetrabromotetraazapyrene (TBTAP) molecules directly adsorbed on Ag(111) into an orientational glassy phase. The electron-deficient TBTAP is singly-occupied by an electron donated from the substrate, resulting in a spin 1/2 state, which is confirmed by a Kondo resonance. The TBTAP•- discharge is controlled by tip-gating and leads to a series of peaks in scanning tunneling spectroscopy. These occurrences are explained by combining a double-barrier tunneling junction with a Franck-Condon model including molecular vibrational modes. This work demonstrates that suitable precursor design enables gate-dependent vibrational excitations of molecules on a metal, thereby providing a method to investigate electron-vibration coupling in molecular assemblies without a decoupling layer.

3,3'-Di-tert-butyl-1,1'-[1,3-phenyl-enebis(methyl-ene)]diurea.

Project description:The title compound, C(18)H(30)N(4)O(2), contains two tert-butyl urea groups, each connected to a benzene ring though a methyl-ene group. One of the groups occupies a position almost normal to the aromatic plane with a C-N-C-C torsion angle of -94.4?(4)°, while the other is considerably twisted from the ring with a C-N-C-C torsion angle of -136.1?(4)°. In the crystal, pairs of mol-ecules are connected to each other, forming centrosymmetric dimers in which two NH groups of one mol-ecule act as hydrogen-bond donors to one carbonyl O atom of the other mol-ecule. The dimers are linked into sheets parallel to (100) by N-H?O hydrogen bonds involving the remaining N-H and C=O groups.
