chloromethylbenzotriazole to give (benzotriazol-1-yl)methyldiphenylphosphine oxide, which, after lithiation, was alkylated to give 1-(benzotriazol-1-yl)alkyldiphenylphosphine oxides in good yield. Treatment of 1-(benzotriazol-1-yl)alkyldiphenylphosphine oxides with n-butyllithium followed by condensation with epoxides, afforded benzotriazol-1-yl-substituted cyclopropanes, which underwent further lithiation
二苯基亚膦酸酯阴离子与氯甲基苯并三唑反应,得到(苯并三唑-1-基)甲基二苯基膦氧化物,其在锂化后被烷基化,以高收率得到1-(苯并三唑-1-基)烷基二苯基膦氧化物。用正丁基锂处理1-(苯并三唑-1-基)烷基二苯基膦氧化物,然后与环氧化物缩合,得到苯并三唑-1-基取代的环丙烷,将其进一步锂化并随后与众多亲电试剂反应以提供各种新型的苯并三唑-1-基取代的环丙烷衍生物。
