Let's avoid the risk! The title transformation has been developed for the synthesis of trifluoromethyl‐substituted cyclopropane derivatives (see scheme). It avoids the preparation of trifluoromethyl diazomethane and merges a number of areas: water as a reaction medium, iron catalysis, and access to reactive intermediates under operationally safe conditions.
让我们避免风险!已开发出标题转化方法,用于合成三氟甲基取代的环丙烷衍生物(请参见方案)。它避免了三氟甲基重氮甲烷的制备,并合并了许多领域:水作为反应介质,铁催化作用以及在操作安全的条件下获得反应性中间体的途径。
