vicinal chloro-/bromohydrins and vicinal dihalides by reaction with the system trihaloisocyanuric acid/triphenylphosphine in acetonitrile under mild and neutral conditions. The reactions proceed smoothly in high yield at room temperature and at reflux, respectively, over a short time. A new synthetic method has been developed for the regioselective conversion of epoxides to vicinal chloro-/bromohydrins
摘要 通过在温和中性条件下与三卤代异氰尿酸/三苯基膦体系反应,已开发出一种新的合成方法,用于将环氧化物区域选择性转化为邻位氯-/溴代醇和邻位二卤化物。反应分别在室温和回流下以高收率顺利进行, 在短时间内。 通过在温和中性条件下与三卤代异氰尿酸/三苯基膦体系反应,已开发出一种新的合成方法,用于将环氧化物区域选择性转化为邻位氯-/溴代醇和邻位二卤化物。反应分别在室温和回流下以高收率顺利进行, 在短时间内。
