Efficacy of C–N Coupling Reactions with a New Multinuclear Copper Complex Catalyst and Its Dissociation into Mononuclear Species

Authors


Abstract

A new tetranuclear copper(I)–pyridazine (pda)/rhenate hybrid has been synthesized under hydrothermal conditions and structurally characterized by X-ray crystallography. The activity of this catalyst, as well as its dissociation into mononuclear species, was investigated in homogeneous C–N arylation reactions. A variety of N-arylamides and -azoles were synthesized in good to excellent yields, revealing the effect of polynuclear versus mononuclear Cu complexation in this type of coupling reaction.
