一种可分离的二烷基亚硅基，2，2，5，5-四（三甲基硅基）硅杂环戊烷-1，1-二基（1）与乙烯、（Z）-2-丁烯、乙炔、双（三甲基硅基）乙炔和2，3-二甲基丁二烯在室温下反应，得到相应的可分离的硅杂环化合物。由于大的空间位阻，1与（E）-2-丁烯的反应得到复杂的混合物，表明没有形成相应的硅烷。1与2，3-二甲基丁二烯反应得到相应的[1 + 4]环加合物，而没有[1 + 2]环加合物的污染。用X射线晶体学方法分析了1与乙烯和乙炔反应生成的稳定的C-未取代的硅烷和硅烯。(C)2011 Wiley Periodicals，Inc.

The reactions of an isolable dialkylsilylene, 2,2,5,5-tetrakis(trimethylsilyl)silacyclopentan-1,1-diyl (1) with ethylene, (Z)-2-butene, acetylene, bis(trimethylsilyl)acetylene, and 2,3-dimethylbutadiene at room temperature gave the corresponding silacycles as isolable compounds. Because of the large steric hindrance, the reaction of 1 with (E)-2-butene gave a complex mixture, indicating no formation of the corresponding silirane. The reaction of 1 with 2,3-dimethylbutadiene afforded the corresponding [1 + 4] cycloadduct without contamination of the [1 + 2] cycloadduct. Stable C-unsubstituted silirane and silirene produced by the reactions of 1 with ethylene and acetylene were analyzed by X-ray crystallography. (C) 2011 Wiley Periodicals, Inc.
