摘要：A process for converting an aromatic compound to prepare an iodoarene, Ar-I, and an aryl compound in which an unsaturated compound is bonded directly to an aryl group, Ar, which process comprises reacting a diaryliodonium salt represented by general formula (I) [Ar - I<(+)> - Ar]X<(-)> (I) wherein Ar is an aryl group which may be substituted and two Ar's are identical and X<(-)> is a counter ion inert to the reaction with the unsaturated compound in a solvent in the presence of a transition metal catalyst and a base or a reducing metal, said reaction being carried out at a temperature not higher than 80 DEG C and/or by using at least one of the base, the reducing metal and the unsaturated compound in an amount not more than 1.5 times the stoichiometric amount, then separating the iodoarene Ar-I thus formed from the reaction mixture, subsequently coupling said iodoarene thus separated with an aromatic compound, ArH, in an oxidizing atmosphere in the presence of X<(-)> or an anion ion-exchangeable with X<(-)>, if needed ion-exchanging the anion with X<(-)>, to form the diaryl iodonium salt of the above general formula (I), and recycling said diaryl iodonium salt thus formed in said reaction.
