dichlorocarbene to alkenes, with Me3Sn− anions are reported. The process is described in terms of a photoinduced SRN1 substitution. The 1,1-bis(trimethylstannyl)cyclopropanes were obtained in good to excellent isolated yield (71−90%); 7,7-dichloro-2-oxa-bicyclo[4.1.0]heptane gave the 1,1-bis(trimethylstannyl) product in only 40% yield.
容易获得的1,1- dichlorocyclopropanes的的反应中,通过加入二氯卡宾为烯烃得到的,与我3的Sn -报道阴离子。根据光诱导的S RN 1取代来描述该过程。得到的1,1-双(三甲基锡烷基)环丙烷的分离收率良好至优异(71-90%);7,7-二氯-2-氧杂双环[4.1.0]庚烷仅以40%的收率得到1,1-双(三甲基锡烷基)产物。
