Diaryl-4,4′-bisdiazonium dichlorides react with olefins in CuCl2 presence to form 4,4′-bisdiazoniumdiaryl tetrachlorocuprates(II) as intermediates. The method of synthesis of these stable complex diazonium salts under ordinary conditions has been worked out. They decompose in polar solvents at room temperature to form 4,4′-dichlorodiaryls in high yield. In the presence of olefins (compounds containing a X = Y bond, acrylates and metacrylates, acrylonitrile, styrene, 1,3-butadiene) they decompose forming adducts, products of chloroarilation of the enumerated substrates to double bond consuming one or two diazogroups. 4-Styryl-4′-chlorodiaryls, the products of arylation by one diazogroup, were obtained from styrene.
