Friedel–Crafts type benzylation of arenes and heteroarenes with benzylic acetates, alcohols, and carbonates is effectively promoted under mild reaction conditions using catalytic amounts of gold salts. The resulting 1,1-diarylalkanes and 1-aryl-1-heteroarylalkanes are obtained in high yields and with high selectivity. The utility of the method is demonstrated by a short synthesis of beclobrate ethyl
在温和的反应条件下,使用催化量的金盐,可有效促进芳烃和杂芳烃与苄基乙酸酯,醇和碳酸盐的Friedel-Crafts型苄基化反应。以高收率和高选择性获得所得的1,1-二芳基烷烃和1-芳基-1-杂芳基烷烃。该方法的实用性通过短纤维酸衍生物2-乙基[4- [4-(4-氯苄基)-苯氧基] -2-甲基丁酸酯(3)}}的合成证明。
