Novel copper(I) complex of 2,5-Bis(2-pyridyl)phosphole: Synthesis, Characterization, Catalytic Activity and DFT Calculations

A copper(I) complex [CuCl{k1(P)-1a}{k2(P,N)-1a}] (1a = 2,5-bis(2-pyridyl)-1-phenylphosphole) with pseudo tetrahedral geometry was synthesized. In solution, 1a displays a hemilabile behaviour leading to a dynamic equilibrium between four and three-coordinate specie. Its catalytic potential was tested in synthesis of propargylamines and 1,2,3-triazoles via three-component reactions. Experimental results discussed on base to DFT calculations.
