An efficient method for N-acylation of amides is described using a pyridine ring as the internal nucleophilic catalyst to give imides in moderate to excellent yields. The methodology provides a facile, air insensitive, and environmentally friendly route to form diversified imide scaffolds, which exist widely in natural products and biologically active materials.

The regioselective RuII-catalyzed direct ortho-arylation of C-3 aryl-substituted imidazo[1,5-a]azines with (hetero)aryl halides was investigated. The employment of RuII and PdII catalysts in the same flask resulted in two sequential and distinct C–H bond arylations, which allowed the rapid synthesis of highly conjugated compounds.
