A Cu-catalyzed selective aerobic heterocoupling of terminal alkynes is disclosed, which enables the synthesis of a broad range of unsymmetrical 1,3-diynes in good to excellent yields. The results disprove the long-held belief that homocouplings are exclusively favored in the Glaser-Hay reaction.

A facile and environmentally friendly synthetic method for a variety of symmetrical 1,3-diyne derivatives based on the Pd/C-CuI-catalyzed homocoupling reaction of terminal alkynes has been developed. The reaction was efficiently catalyzed by the extremely

The mass spectral behavior of 1,6-bis(arylsulfenyl)-2,4-hexadiynes and 1,6-bis(arylsulfonyl)-2,4-hexadiynes were examined.The sulfenyl derivatives extruded the hexadiynyl moiety with the formation of Ar-S-S-Ar fragments.The sulfonyl derivatives, on the other hand, showed no extrusion of the hexadiyne fragment but an expulsion of SO2 and even two SO2 units.
