A novel Pd-catalyzed nitrogenation of arylpyridines via C-H azidation has been developed. Direct C-N and N-N formations are achieved for this N-atom incorporation transformation using azides as the N-atom source. This method provides an alternatively concise approach for the construction of bioactively important pyrido[1,2-b]indazoles.

Reactions of benzyne with several pyridinium N-imines were examined. 2-o-Aminophenylpyridine derivatives 6, pyridoindazoles (7), indazoloquinoline (17), and indazoloisoquinoline (18) were obtained by the reactions of benzyne with the
