alkyl- and aryllithium reagents for the preparation of organosilyl ethyl ethers of the type R3SiOEt, R2R′SiOEt, and R2Si(OEt)2, that can be reduced to the organosilanes R3SiH, R2R′SiH, and R2SiH2, respectively. Compounds of the type RR′R′SiOEt cannot be cleanly formed. The reduction procedure involves treatment of the silyl alkoxy ethers with diisobutylaluminium hydride (DIBALH) and hydrolysis of the remaining
四烷基硅烷用烷基和芳基锂试剂处理,以制备R 3 SiOEt,R 2 R'SiOEt和R 2 Si(OEt)2类型的有机甲硅烷基乙基醚,可以将其还原为有机硅烷R 3 SiH,R分别为2 R'SiH和R 2 SiH 2。不能清晰地形成RR'R'SiOEt类型的化合物。还原步骤包括用氢化二异丁基铝(DIBALH)处理甲硅烷基烷氧基醚,并用Na 2 SO 4 ·10H 2 O水解剩余的烷基铝化合物。这种水解为分离R3 SiH,R 2 R'SiH和R 2 SiH 2化合物,没有发生SiH部分水解,这在无阻硅烷的标准水处理程序中经常发生。
