2-Trimethylsilylmethylenecyclopropane (=3) was synthesized by reaction of lithio methylenecyclopropane with TMSCl. The lithium salt of (=3) reacts with some electrophiles by α- or γ-attack depending on the nature of the electrophile. Whereas alkenylbromides 8 and 9 or alkinylbromide 10 give exclusively α-attack, benzaldehyde reacts with γ-alkylation.
通过使硫代亚甲基环丙烷与TMSC1反应合成2-三甲基甲硅烷基亚甲基环丙烷(= 3)。(= 3)的锂盐根据亲电试剂的性质,通过α或γ攻击与某些亲电试剂反应。烯基溴化物8和9或炔基溴化物10仅产生α-攻击,而苯甲醛与γ-烷基化反应。
