dissolves into warm hexamethylphosphoric triamide to give a black solution, in which polymethylated iodobenzenes undergo nucleophilic attack by azide and selenocyanate ions, giving the corresponding aryl azides and selenocyanates in low to good yields. In the absence of copper(I) salt, however, the reaction does not take place. Cyanide, cyanate, thiocyanate, and fluoride ions bring about a decoloration of
碘化铜 (I) 溶解在温热的六甲基磷酰胺中得到黑色溶液,其中多甲基化碘苯受到叠氮化物和硒氰酸根离子的亲核攻击,得到相应的芳基叠氮化物和硒氰酸盐,产率从低到高。然而,在不存在铜 (I) 盐的情况下,反应不会发生。氰化物、氰酸根、硫氰酸根和氟离子使反应混合物脱色,不会发生置换反应,而碲氰酸根离子在释放元素碲的同时提供相应的芳基氰化物。
