in quantitative yields using the copper(II) acetate catalyzed homocoupling of terminalalkynes in the presence of a stoichiometric amount of piperidine at 25 ˚C under aerobic conditions. We also accomplished facile syntheses of unsymmetric 1,3-diynes by heterocouplingterminalalkynes in very good yields under the reported reaction conditions. terminalalkynes - copper(II) acetate - piperidine - homocoupling
