Abstract

Dehydrogenative desulfurization of thiourea derivatives (RNHC(S)NHR') has been achieved, to give carbodiimides (RN=C=NR'), in the reaction with hydrosilane and (η(5)-C5H5)Fe(CO)2Me. The obtained carbodiimide reacted with (η(5)-C5H5)Fe(CO)(SiR3) formed in the reaction to give an N-silylated η(2)-amidino iron complex, which was isolated and then characterized by X-ray analysis.
