bond‐functionalization reactions of arenes offer the potential for a more benign synthesis of fine chemicals and organic building blocks for the life science industries. In this respect, direct carbonylative coupling reactions of (hetero)arenes allow for the straightforward synthesis of (hetero)aromatic ketones and related derivatives. Herein, we present an efficient ruthenium(II)‐catalyzed carbonylative hydroarylation
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.
