Introduction of aryl and heteroaryl groups onto 1-azaazulene ring was achieved by addition-elimination reaction and Suzuki coupling. Reaction of 2-chloro-1-azaazulenes with 2-aryllithium and 2-heteroaryllithium followed by dehydrogenation with o-chloranil

Substituted 1-azaazulenes are synthesized from cycloheptatrienylmethyl ketone O-pentafluorobenzoyloximes by the intra-molecular Heck-type amination catalyzed by Pd(dba)2-(t-Bu)3P.
Synthesis and reactivity of N-diphenylphosphinoyltroponimine: Synthetic entry into 1-azaazulene derivatives

A novel N-diphenylphosphinoyltroponimine (5), which is highly polarized and has a low lying LUMO, was prepared. The attempted reaction of 5 with enolate ions and enamines derived from cyclic ketones gave 1-azaazulene derivatives, albeit in low yields.
