The reactions of sterically less hindered α-bromo alkyl and aryl ketones with tetrasulfur tetranitride·antimony pentachloride (S4N4·SbCl3) complex in toluene at reflux gave the corresponding α-chloro ketones in good to excellent yields.
在甲苯中,空间受阻较少的α-溴代烷基和芳基酮与四氮化四硫·五氯化锑(S 4 N 4 ·SbCl 3)配合物在回流下反应,得到相应的α-氯代酮,收率良好至优异。
