Palladium-Catalyzed Synthesis of 1-Azaazulenes from Cycloheptatrienylmethyl Ketone O-Pentafluorobenzoyl Oximes

Abstract
Substituted 1-azaazulenes are synthesized from cycloheptatrienylmethyl ketone O-pentafluorobenzoyloximes by the intramolecular Heck-type amination catalyzed by Pd(dba)2–(t-Bu)3P.
