Treatment of alkylbenzenes with (diacetoxyiodo)benzene in the presence of catalytic amounts of p-toluenesulfonamide or p-nitrobenzenesulfonamide, and molecular iodine in 1,2-dichloroethane at 60 °C gave the corresponding (α-acetoxy)alkylbenzenes in good to moderate yields. The present reaction is a simple method for the introduction of an acetoxy group to the benzylic position of alkylbenzenes.
在催化量的对甲苯磺酰胺或对硝基苯磺酰胺的存在下,用(二乙酰氧基碘)苯处理烷基苯,在60°C下于1,2-二氯乙烷中用分子碘制得相应的(α-乙酰氧基)烷基苯。本反应是将乙酰氧基引入烷基苯的苄基位置的简单方法。
