functionalities for drug development. Despite significant accomplishments in the trifluoromethylthiolation, trifluoromethylation and difluoromethylation reactions, directly converting common functional groups into CF3S, CF3 or HCF2 groups is still highly desirable. Described here is the dehydroxylative trifluoromethylthiolation, trifluoromethylation and difluoromethylation of alcohols promoted by a R3P/ICH2CH2I
CF 3 S,CF 3和HCF 2基团已被确定为药物开发的有价值的功能。尽管在三氟甲基硫醇化,三氟甲基化和二氟甲基化反应方面取得了重大成就,仍然非常需要将常见的官能团直接转化为CF 3 S,CF 3或HCF 2基团。在此描述的是由R 3 P / ICH 2 CH 2 I体系促进的醇的脱羟基三氟甲基硫醇化,三氟甲基化和二氟甲基化。所有这些脱羟基反应都是在温和条件下通过R活化羟基而实现的3 P / ICH 2 CH 2 I系统。观察到较宽的底物范围和良好的官能团耐受性。
