Abstract

Aryl(cyano)iodonium triflates (ArI+CN -OTf, Ar = Ph, 4-CF3C6H4, 3,5-(CF3)2C6H3, 4-FC6H4) can be prepared in two steps from the corresponding aryliodides by oxidation with pertrifluoroacetic acid and subsequent reaction with Me3SiOTf and Me3SiCN. These compounds react with tributyltin derivatives of acetylenes, aromatic or heteroaromatic compounds under mild conditions forming the corresponding iodonium salts 5, 7, 9 in good yield.
