Exploiting the dual role of ethynylbenziodoxolones in gold-catalyzed C(sp)-C(sp) cross-coupling reactions

Reported herein is the gold-catalyzed alkynylation of terminal alkynes using ethynylbenziodoxolones (EBXs), where EBXs serve a dual role as oxidants as well as alkyne transfer agents to access unsymmetrical 1,3-diynes. Hence, the catalytic system requires no external oxidants and is compatible with a broad range of substrates, including those with polar functional groups such as NH, OH and B(OH)2.

Nickel-catalyzed cross-coupling reaction of acetylenic sulfones with alkynyl Grignard reagents: A facile method for the preparation of unsymmetrical 1,3-diynes

The cross-coupling reaction of acetylenic sulfones with acetylenic Grignard reagents was realized by using Ni(acac)2 as catalyst to afford unsymmetrical 1,3-diynes under mild conditions without homocoupling byproducts. By using this method, 1,4-diaryl-1,3-diynes could be obtained in moderate to good yields (59-83%), whereas, the yields for alkyl substituted 1,3-diynes are lower (30-54%).
