were utilized as reusable homogeneous catalysts in A3 coupling reactions involving aldehydes, amines and phenyl acetylene for the synthesis of propargylamines under solvent-free conditions. Particularly, complex 2 has been found to be highly efficient in the synthesis of propargylamines. Many novel compounds have been synthesized based on A3 coupling reaction and the formation of new compounds was confirmed
