✦ Synopsis

I,I,2,2-Tetramethyldisilane reacts with Fez(CO)9 to yield bis(u-dimethylsilylene)-u-car-bony1 bis(tricar-bonylironJ(Fe-Fe). Reaction with octacarbonyldicobalt analogously gives bis(u-dimethylsilylene)bis-(tricarbonylcobalt)(Co-Co) as stable product; spectroscopic results also indicate inter alia the formation of (tetramethyldisilyl)tetracarbonylcobalt, u_(dimethylsilylene)-~-carbonyl-bis(tricarbonyl)cobalt(Co-Co), and cobalt cluster compounds. Reactivity of zerovalent transition metal compounds toward Si-Si bonds seems to be greatest for the nickel triad and to decrease as one moves from right to left across the transition series.
