Lithiated 화합물인 Cl2Si=CHCH2tBu로부터 LiCl의 제거반응에 의해 생성된 준안정 반응중간체인 Silaethene, Cl2Si=CHCH2tBu은 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.

Silaethene Cl2Si=CHCH2tBu, generated as a metastable reaction intermediate by the thermal eliminatio of LiCl from lithiated compound Cl2Si=CHCH2tBu, 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.
