Homocoupling of terminal alkynes with copper catalysts

The homogeneous and heterogeneous copper-based catalysts used in the homocoupling reaction of terminal alkynes in recent years were reviewed in details, including Cu(I), Cu(II)and CuNPs catalysts. The catalytic performances of the catalysts were compared from the following aspects: the optimal reaction condition, life and substrate scope. Besides the reaction mechanisms of catalysts were explained. It was known that the supported Cu(II) heterogeneous catalysts could be the research direction for homocoupling of terminal alkynes in respect that they were steady and easily prepared. Further more, the reactions were carried out efficiently under the mild condition.
