Abstract
The base-stabilized silylene complex (eta (5)-C5H5)Fe(CO)(eta (2)-SiMe2-(OB u)-Bu-t-SiMe2) is unreactive toward (Me3Si)(3)EH (E = Si, Ge) under photoch emical irradiation or at room temperature. However, at 80 degreesC it react s, presumably via the equilibrium concentration of base-free complex (eta ( 5)-C5H5)Fe(CO)((SiMe2OBu)-Bu-t)(=SiMe2), to transfer the silylene group and form (Me3Si)(3)ESiMe2H. Attempts to transfer the SiMe2 group to tributylti n hydride led to formation of bis(tributylstannyl)iron completes.
