Abstract

From the reaction of phenyltrimethylsilylacetylene with lithium, 1,4-bis(trimethylsilyl)-2,3-diphenyl-1,4-butadene dianion was formed. The reaction of dianion with dichlorodimethylsilane affords 1,1-dimethyl-2,5-bis(trimethylsilyl)-3,4-diphenyl-1-silacyclopenta-2,4-diene. In addition 1,4-bis(trimethylsilyl)-2,3-diphenyl-1,3-butadiene was isolated. It seems to be hydrolized product in alkali medium.

Phenyltrimethylsilylacetylene과 리듐의 반응으로 부터 1,4-bis(trimethylsilyl)-2,3-diphenyl-1,4-butadene dianion이 형성되었다. 이 반응생성물과 dichlorodimethylsilane을 반응시키면 1,1-dimethyl-2,5-bis(trimethylsilyl)-3,4-diphenyl-1-silacyclopenta-2,4-diene이 얻어졌다. 이와 함께 분리된 1,4-bis(trimethylsilyl)-2,3-diphenyl-1,3-butadiene은 알칼리 매질에서 가수분해되어 생성된 화합물로 보인다.
