A new catalyst for cross-coupling synthesis of 1,4-diphenylbutadiyne-1,3 was prepared by thermolysis of copper(II) poly-5-vinyltetrazolate. It presents heterogeneous catalyst, in which copper nanoparticles are supported on polymeric matrix surface. The catalyst is recovered, recycled, and shows high catalytic activity in cross-coupling synthesis of 1,4-diphenylbutadiyne-1,3. The reaction proceeds in aerobic conditions at room temperature in the presence of pyridine.
