α－溴代乙酸苯酯合成的新方法

A New Method of Synthesizing Phenyl-α-bromo Acetate

将亚硫酰氯与乙酸反应制得的乙酰氯与溴作用生成α－溴代乙酰氯，然后在溶剂中与苯酚或其钠盐作用生成α－溴代乙酸苯酯。该法副反应少产率高，消耗较少的澳，产品成本较低。

Pheny-α-bromo acetate is synthesized in higher yield from Br_2 as acyl agent in three steps.This route has the advantages of a small quantity of Br_2 and lower cost of product.
