ABSTRACT
A facile and novel copper-catalyzed decarboxylative coupling of various arylpropiolic acids with readily available dialkyl hydrazinylphosphonates has been developed, providing an attractive synthetic tool for the synthesis of valuable alkynylphosphonates with operational simplicity and mild reaction conditions.
