Desulfurization of N,N-dimethylthioformamide by hydrosilane with the help of an iron complex. Isolation and characterization of an iron-carbene complex as an intermediate of C=double bond cleavage.
Desulfurization of N,N-dimethylthioformamide (Me(2)NCHS) 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=S bond to give a carbene-iron complex. This intermediate was isolated and characterized by X-ray analysis.
