Synthesis of ruthenium N-heterocyclic carbene complexes and their catalytic activity for β-alkylation of tertiary cyclic amines

Abstract : The novel ruthenium N-Heterocyclic carbene complexes are synthesized, and characterized by studying its 1H, 13C, elemental analysis, and X-ray. These complexes have been reported as promising catalyst for β C–H bond functionalization of tertiary cyclic amines through hydrogen autotransfers in the presence of external acidic additive. The new catalytic products were characterized by 1H NMR, 13C NMR spectroscopic methods
