摘要
Functional hydrosilanediyl-transition metal complexes, ArSi(D)H=ML(n) (with D = Lewis base), are obtained, in excellent yield, by the photochemical coupling reaction of ArSiH3 with Fe(CO)5, Cr(CO)6, or RCpMn(CO)3 (R = H, Me), in the presence of either internal (D = [(NN-dimethylamino)methyl]phenyl group) or external (D = NN-dimethylimidazolidinone) nucleophiles. Unexpectedly, the Lewis base character of N,N-dimethylimidazolidinone (DMI) is strong enough to quantitatively convert dimeric [Fe2(CO)8(SiPh2)2] to the more stable [Ph2Si(DMI)=Fe(CO)4].
