Beschreibungen/Notizen

• An efficient Rh I -NHC-pincer catalyst for the highly regioselective Meinwald rearrangement of monoalkylated epoxides into methylketones under mild conditions is presented. The nucleophilic epoxide opening is assisted by Lewis acids. The highly nucleophilic complex 1 isomerises terminal epoxides exclusively to the respective methylketones in very high yield under mild conditions.
