Palladium(0)-Catalyzed Amino-Heck Reaction Of Y,8-Unsaturated Ketone N,N,N-Trimethylhydrazonium Salts

摘要

Oxidative addition of N,N,N-trialkylhydrazonium salts takes place to a palladium(O) complex, resulting the formation of alkylideneaminopalladium(II) species. This N-N bond scission process is applied to the transformation of gamma,delta-unsaturated ketone hydrazonium salts to pyrroles by amino-Heck reaction.
