Abstract

An isolated reaction intermediate in the desulfurization of thiones promoted by phosphanes is provided by the ylide derivative 3, which is obtained by thiophilic addition of PCy3 to 2. Complex 2 is formed from the disulfide-containing dimetallic complex 1 by scission of the S−S bond. [Mn]=Mn(CO)4+, R=Ph.
