A process for arylating an olefinic compound by addition of an aryl group to a double bond of said olefinic compound consisting in diazotizing an arylamine in an aqueous acidic solution comprising a lower alkanoic acid to form a solution of an aryldiazonium salt and reacting said aryldiazonium salt solution with an olefinic compound in an organic solvent in the presence of a catalytically effective amount of a copper halide. The amount of alkanoic acid is about 15 to 37% by volume of the total solvents used. The alkanoic acid is preferably acetic acid and the copper halide cuprous chloride.
一种芳基化烯烃化合物的方法,通过将芳基基团加到所述烯烃化合物的双键上,包括在含有较低的烷酸的水溶性酸性溶液中重氮化芳胺,以形成一种芳基重氮盐溶液,并在有机溶剂中,在催化剂作用下的有效量的卤化铜的存在下,将所述芳基重氮盐溶液与烯烃化合物反应。烷酸的量为所用溶剂总量的约15%至37%体积。烷酸最好是乙酸,卤化铜最好是氯化亚铜。
