Iron-catalyzed cyclopropanation with trifluoroethylamine hydrochloride and olefins in aqueous media: in situ generation of trifluoromethyl diazomethane
摘要:
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.
