A stereospecific triphenylphosphine oxide-catalyzed 1,2-dichlorination reaction of epoxides has been developed. The reaction is effective for a range of terminal and internal epoxides. In contrast to the classical Appel-type dichlorination of epoxides, oxalyl chloride is used as a stoichiometric reagent to generate the chlorophosphonium salt responsible for dichlorination from catalytic triphenylphosphine
已经开发了立体有择的三苯基膦氧化物催化的1,2-二氯化环氧化物。该反应对于一定范围的末端和内部环氧化物是有效的。与经典的Appel型环氧化物二氯化相反,草酰氯用作化学计量试剂,用于从催化三苯膦氧化物生成负责二氯化作用的氯盐。
