Treatment of Mn(CO)5SiTolp 2H (2) with an excess of LiAlH4, NaBH4, or NaBH3(CN) in THF at room temperature gave hydrosilane H-SiTolp 2H in high yield together with Mn2(CO)10. No reduction of CO ligands was observed. On the other hand, treatment of 2 with an excess of Red-Al ( = with LiAlH4 in diethyl ether instead of hydrolysis gave alkylhydrosilanes (CH3)SiTolp 2H and (C2H5)SiTolp 2H. The methyl and ethyl groups on silicon originate from the CO ligands in 2. These products clearly demonstrate that not only the Si-C coupling, but also C-C coupling occurs efficiently in this reaction.
