Manganese(III)-promoted thiocarbonylation of alkylborates with disulfides: synthesis of aliphatic thioesters

Copper-catalyzed thiocarbonylation and thiolation of alkyl iodides

In the present study, an efficient Cu-catalyzed transthiolation of alkyl iodides is developed. Notably, in the presence of CO, thioesters could also be obtained with copper and cobalt as the co-catalyst. This transformation displayed good functional group tolerance and afforded thioesters or sulfides from the corresponding alkyl iodides.

Acid catalysis through N-protonation in undistorted carboxamides: improvement of amide proton sponge acylating ability

Acid catalysis of weakly distorted or undistorted carboxamides in acyl-migration reactions proceeding through N-protonation is the process with low probability in contrast to O-protonation. This circumstance made the experimental study...
