Copper-catalyzed regioselective reaction of internal alkynes and diaryliodonium salts

Xu, Ze-Feng,Cai, Chen-Xin,Liu, Jin-Tao

supporting information, p. 2096 - 2099 (2013/06/05)

The copper-catalyzed highly regioselective reaction of internal alkynes with diaryliodonium salts was achieved for the first time. α-Arylketones were obtained in moderate to good yields from arylpropargylic alcohols or aryl alkyl alkynes under mild condit
