An efficient Friedel–Crafts alkylation of aromatic compounds with ethyl α-chloro-α-(ethylthio)acetate catalysed by ytterbium triflate, followed by desulfurisation of the product provides a convenient methodology for the synthesis of ethyl arylacetates of aromatic and heteroaromatic compounds.
用三氟甲磺酸催化的α-氯-α-(乙硫基)乙酸乙酯对芳族化合物进行有效的弗里德-克拉夫茨烷基化反应,然后产物进行脱硫,为合成芳族和杂芳族化合物的芳基乙酸乙酯提供了便利的方法。
