Activation of C-C Bonds via σ-Bond Metathesis: Hydroborenium-Catalyzed Hydrogenolysis of Cyclopropanes

High-valent transition metal or main group complex mediated σ-bond metathesis plays an important role in the activation of covalent H-E bonds. However, its involvement in the activation of C-C bonds has remained elusive. Here we describe direct hydroboration of the C-C bonds of cyclopropanes by a hydroborenium complex. Our mechanism study suggests this reaction operates through a σ-bond metathesis pathway. With this hydroborenium complex as a catalyst, hydrogenolysis of unfunctionalized cyclopropanes was achieved, which is unprecedented for homogeneous catalysts and provides an unconventional approach for C-C bond functionalization in the absence of metals.

Organolanthanide catalyzed hydrogenation and hydrosilylation of substituted methylenecycloalkanes

This communication presents a study of the scope of the catalytic hydrogenation and hydrosilylation of chiral exomethylene-substituted cyclopentanes and cyclohexanes utilizing the organolanthanide precatalysts Cp2* LnCH(SiMe3)2 (Cp* = C5Me5; Ln = Sm, Yb). Both reaction types are sterically driven and lead to the cis-diastereomer as the major product. Additionally, the hydrosilylation is regiospecific, the silane being placed exclusively at the terminal position of the double bond.

PHOTOCHEMISTRY OF N-ACYLAZOLES. VI). PHOTOREACTIVITIES OF 1-ACYL-1,2,4-TRIAZOLES AND OF 2-ACYLTETRAZOLES

Contrary to the findings in the photolysis of N-acylimidazoles (2) irradiation of 1-acyl-1,2,4-triazoles afforded no photo-Fries product, but instead products formed via the corresponding acyl radicals and aldehydes.Photolysis of 2-acyltetrazoles gave in part the same products as those obtained from the irradiation of the corresponding acyl-triazoles as well as 2-alkyl-1,3,4-oxadiazoles.N-Acyltetrazoles didn't give any photo-Fries product neither.
