Methyl 2-silabicyclo[2.1.0]pentane-1-carboxylate, obtained by a photochemical intramolecular cyclopropanation reaction of an [small alpha]-allylsilyl-[small alpha]-diazoacetate, undergoes ring opening reactions under different conditions leading to methyl 2-[diisopropyl(methoxy)silylmethyl]cyclopropane-1-carboxylate, a 1-sila-4-cyclopentene-2-carboxylate or an allyl(methoxysilyl)ketene.
通过小α-烯丙基甲硅烷基-小α-重氮乙酸酯的光化学分子内环丙烷化反应获得的2-甲硅烷基环[2.1.0]戊烷-1-羧酸甲酯在不同条件下进行开环反应,生成2-甲基[二异丙基(甲氧基)甲硅烷基甲基]环丙烷-1-羧酸酯,1-sila-4-环戊烯-2-羧酸酯或烯丙基(甲氧基甲硅烷基)烯酮。
