Abstract

The base-stabilized silylene complex (η5-C5H5)Fe(CO)(η2-SiMe2-OtBu-SiMe2) is unreactive toward (Me3Si)3EH (E = Si, Ge) under photochemical irradiation or at room temperature. However, at 80 °C it reacts, presumably via the equilibrium concentration of base-free complex (η5-C5H5)Fe(CO)(SiMe2OtBu)(SiMe2), to transfer the silylene group and form (Me3Si)3ESiMe2H. Attempts to transfer the SiMe2 group to tributyltin hydride led to formation of bis(tributylstannyl)iron complexes.
