【摘要】 邻溴苯乙酸的一种新合成路线，通过对磺酸基苯乙酸的溴代反应和２一溴一４一磺酸基苯乙酸的水解反应脱去磺酸基来完成。对磺酸基苯乙酸则由苯乙酸与三氧化硫的磺化反应制备。产品经熔点、￣１ＨＮＭＲ和元素分析测定。更多还原

【Abstract】 new synthetic process of O bromobenzeneacetic acid was accomplished through bromizationof p sulfobenzeacetic acid and hydrolysis of 2 bromo 4 sulfobenzeneacetic acid with sulfo re-moved.P sulfobenzeneacetic acid was prepared through sulfonation of benzeneacetic acid and sulfurtrioxide, The products were tested from the melting point 1HNMR and element analysis.更多还原
