Nickel/Photoredox-Catalyzed Amidation via Alkylsilicates and Isocyanates.

ABSTRACT: A nickel/photoredox, dual-catalyzed amidation reaction between alkylsilicate reagents and alkyl/aryl isocyanates is reported. In contrast to the previously reported reductive coupling process, this protocol is characterized by mild reaction conditions and the absence of a stoichiometric reductant. A mechanistic hypothesis involving a nickel-isocyanate adduct is proposed based on literature precedent and further validation by experimental results.

Cobalt(III)-Catalyzed C-H Bond Amidation with Isocyanates.

Project description:The first examples of cobalt(III)-catalyzed C-H bond addition to isocyanates are described, providing a convergent strategy for arene and heteroarene amidation. Using a robust air- and moisture-stable catalyst, this transformation demonstrates a broad isocyanate scope and good functional-group compatibility and has been performed on gram scale.

Base-Free Photoredox/Nickel Dual-Catalytic Cross-Coupling of Ammonium Alkylsilicates.

Project description:Single-electron transmetalation is recognized as an enabling technology for the mild transfer of alkyl groups to transition metal catalysts in cross-coupling reactions. Hypercoordinate silicates represent a new and improved class of radical precursors because of their low oxidation potentials and the innocuous byproducts generated upon oxidation. Herein, we report the cross-coupling of secondary and primary ammonium alkylsilicates with (hetero)aryl bromides in good to excellent yields. The base-free conditions have exceptional protic group tolerance on both partners, permitting the cross-coupling of unprotected primary and secondary amines.

Phenol Derivatives as Coupling Partners with Alkylsilicates in Photoredox/Nickel Dual Catalysis.

Project description:Photoredox/nickel dual catalysis via single electron transmetalation allows coupling of Csp(3)-Csp(2) hybridized centers under mild conditions. A procedure for the coupling of electron-deficient aryl triflates, -tosylates, and -mesylates with alkylbis(catecholato)silicates is presented. This method represents the first example of the use of phenol derivatives as electrophilic coupling partners in photoredox/nickel dual catalysis.

Engaging Alkenyl Halides with Alkylsilicates via Photoredox Dual Catalysis.

Project description:Single-electron transmetalation via photoredox/nickel dual catalysis provides the opportunity for the construction of Csp(3)-Csp(2) bonds through the transfer of alkyl radicals under very mild reaction conditions. A general procedure for the cross-coupling of primary and secondary (bis-catecholato)alkylsilicates with alkenyl halides is presented. The developed method allows not only alkenyl bromides and iodides but also previously underexplored alkenyl chlorides to be employed.

Project description:A new photocatalyzed route to amides from alcohols and amines mediated by visible light is presented. The reaction is carried out in ethyl acetate as a solvent. Ethyl acetate can be defined a green and bio-based solvent. The starting materials such as the energy source are easily available, stable, and inexpensive. The reaction has shown to be general and high yielding.

Nickel-catalyzed cycloadditive couplings of enynes and isocyanates.

Project description:A mild and general route for preparing dienamides is described. Nickel imidazolylidene complexes were used to mediate cycloadditive coupling between enynes and isocyanates. Dienamides were prepared in excellent yields and with good E:Z selectivity. These dienamides can be further manipulated through oxidative cyclization methods. When a terminal enyne is employed, cyclization affords a lactam rather than a dienamide.

Nickel-catalyzed synthesis of acrylamides from alpha-olefins and isocyanates.

Project description:[reaction: see text] The nickel(0)-catalyzed coupling of alpha-olefins and isocyanates proceeds in the presence of the N-heterocyclic carbene ligand IPr to provide alpha,beta-unsaturated amides. Carbon-carbon bond formation occurs preferentially at the 2-position of the olefin. The N-tert-butyl amide products can be converted to the corresponding primary amides under acidic conditions.

Nickel/photoredox dual catalyzed arylalkylation of nonactivated alkenes.

Project description:Alkene dicarbofunctionalization is an efficient strategy and operation-economic fashion for introducing complexity in molecules. A nickel/photoredox dual catalyzed arylalkylation of nonactivated alkenes for the simultaneous construction of one C(sp3)-C(sp3) bond and one C(sp3)-C(sp2) bond has been developed. The mild catalytic method provided valuable indanethylamine derivatives with wide substrate scope and good functional group compatibility. An enantioselective dicarbofunctionalization was also achieved with pyridine-oxazoline as a ligand. The efficiency of metallaphotoredox dicarbofunctionalization was demonstrated for the concise synthesis of pharmaceutically active compounds.

Dual Nickel/Photoredox-Catalyzed Asymmetric Carbosulfonylation of Alkenes.

Project description:An asymmetric three-component carbosulfonylation of alkenes is presented here. The reaction, involving the simultaneous formation of a C-C and a C-S bond across the π-system, uses a dual nickel/photoredox catalytic system to produce both β-aryl and β-alkenyl sulfones in high yields and with excellent levels of stereocontrol (up to 99:1 er). This protocol exhibits a broad substrate scope and excellent functional group tolerance and its synthetic potential has been demonstrated by successful applications toward pharmacologically relevant molecules. A broad array of control experiments supports the involvement of a secondary alkyl radical intermediate generated through radical addition of a sulfonyl radical to the double bond. Moreover, stoichiometric and cross-over experiments further suggest an underlying Ni(0)/Ni(I)/Ni(III) pathway operative in these transformations.
