五甲基环戊二烯基硅烷的合成

Syntheses of 1,2,3,4,5-pentamethylcyclopentadienyl-organochlorosilanes

五甲基环戊二烯是最重要的配位体,它通过电子效应和空间位阻能够稳定高价氧化态的金属,本文研究了五甲基环戊二烯锂与卤代硅烷反应,合成了6种五甲基环戊二烯基硅烷(2～7)。

1,2,3,4,5-pentamethylcydopentadienylorganocMorosilanes(2-7) have been prepared by the reaction of pentamethylcyclodienyl lithium with organochlorosilanes, and their elemental analysis, 1H, 13C and 29Si NMR, and MS have been determined.
