The reduction of a molybdenum monodithiolene complex, [Mo(CO)₂(dt)(dppe)], in the presence of dichloromethane leads to the transfer of CH₂ to sulfur and respective sulfonium species. Detailed analytical and mechanistical spectroscopic and electrochemical studies reveal the reasons for the unexpected formation and composition of the very unusual resultant complexes to be electronic–energetic in nature.
