Abstract

Desulfurization of N,N-dimethylthioformamide (Me2NCHS) by hydrosilane has been achieved under photo irradiation in the presence of a methyl iron complex. The reaction sequences have been proposed, in which silyl migration from Fe to S of thioformamide triggers the cleavage of a C[double bond, length as m-dash]S bond to give a carbene–iron complex. This intermediate was isolated and characterized by X-ray analysis.
