Abstract

Silaethene $Cl_2$Si=$CHCH_2^tBu$, generated as a metastable reaction intermediate by the thermal eliminatio of LiCl from lithiated compound $Cl_2$Si=$CHCH_2^tBu$, react with propene, 2-methylpropene, 1,3-butadiene, 2,3-dimethyl-1,3-butadiene, and anthracene to give ene-reaction product, 2+2-, and 2+4-cycloadducts. They are isolated by vacuum fractional distillation method and spectroscopically identified.

Lithiated 화합물인 $Cl_3$Si=$CHCH_2^tBu$로부터 LiCl의 제거반응에 의해 생성된 준안정 반응중간체인 Silaethene, $Cl_2$Si=$CHCH_2^tBu$은 propene, 2-methylpropene, 1,3-butadiene, 2,3-dimethyl-1,3-butadiene, anthracene과 반응하여 엔반응 생성물, 2 + 2-, 2 + 4- 고리화부가생성물을 생성한다. 이들을 분별진공증류법에 의해 분리하였고 분광학적으로 확인하였다.
