high yield together with HSiR3. Reaction of CpFe(CO)2SiMes2H with LiAlH4 afforded only H2SiMes2. Labeling experiments using LiAlD4 gave the deuterated methylsilanes. These results proved that the hydrogen source for the methyl group is LiAlH4. Furthermore, the reduction of CpFe(*CO)2SipTol2R‘ (*C = 13C enriched; R‘ = H, Me) produced *CH3SipTol2R‘ where the methyl group introduced on Si was 13C-enriched
CPFe的量的处理(CO)2 SIR 3(CP =η 5 -C 5 H ^ 5 ; R 3 = pTol 2 Cl,pTol 2 H,pTol 2 Me,MePh(1-Nap)和(n -C 5 H 11)2 H; 在室温下用LiAlH 4在
