Abstract
The divalent organosilicon compounds (C5Me5)(2)Si (Cp-2*Si) and (SiNBuCHCHNBu)-Bu-t-Bu-t (SiL2N) have been compared concerning their reactivity toward metallocene derivatives of molybdenum and tungsten. While Cp-2*Si does not react with Cp2MH2 (M = Mo, W), either thermally or photochemically, the reaction of SiL2N with Cp2MH2 leads via silanediyl insertion to Cp2M(H)((SiL2H)-H-N) (M = Mo (1a), W (1b)). Irradiation of a mixture of Cp2Mo(PEt3) and Cp-2*Si yields only decomposition products, whereas photolysis of equimolar amounts of Cp2Mo(PEt3) and SiL2N results in the formation of the silanediyl complex Cp2Mo(SiL2N) (2). 2 is extremely moisture sensitive and easily adds one molecule of water to yield the metallosilanol Cp2Mo(H)((SiL2OH)-O-N) (3). 1a and 2 have been characterized by X-ray crystallography. 2 is the first molybdenum silanediyl complex with a tricoordinated silicon atom. The silicon-molybdenum interaction in 2 has to be described as a dative bond from the silicon to the metal atom.
