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 conditions. It was found that the two kinds of substrates underwent two different arylation–oxygenation pathways under different reaction conditions based
Selective and efficient: The copper(II)‐catalyzed selective monoarylation of vicinaldiols with diaryliodonium triflates was successfully developed. In this catalytic process high chemoselectivity was achieved, even in the presence of a 1:1 mixture of the 1,2‐diol and the mono‐ol, and a wide range of substrates was tolerated, giving the monoarylated products in good to excellent yields (see scheme)

An enantioselective arylation-cyclization cascade has been accomplished using a combination of diaryliodonium salts and asymmetric copper catalysis. These mild catalytic conditions provide a new strategy for the enantioselective construction of pyrroloindolines, an important alkaloid structural motif that is commonly found among biologically active natural products.

A new and mild synthetic approach for the synthesis of N-arylsulfonamides under copper-catalyzed conditions at room temperature has been developed. The reaction employs various tert-butyl N-sulfonylcarbamates and diaryliodoniumsalts to avoid potential genotoxic impurities. A one-pot coupling/Boc-deprotection sequence is also reported to provide mono N-arylsulfonamides in good to excellent yields.
