Various 1-azaazulenes are synthesized from cycloheptatrienylmethyl ketone O-pentafluorobenzoyloximes by treatment with a catalytic amount of Pd(dba)2–t-Bu3P (dba = dibenzylideneacetone) and triethy...
Substituted 1-azaazulenes are synthesized from cycloheptatrienylmethyl ketone O-pentafluorobenzoyloximes by the intramolecular Heck-type amination catalyzed by Pd(dba)2–(t-Bu)3P.
