摘　　要：2-甲氧羰基苯磺酰氯是合成除草剂氟嘧磺隆的一个重要中间体,以2-氯苯甲酸为原料,经亲核取代、酯化、氧化反应制得2-甲氧羰基苯磺酰氯,总收率48.9%,目标化合物的结构经IR、1HNMR、13CNMR、熔点测定进行了表征。2-Methoxycarbonylphenylsulphonic chloride which was an important intermediate of herbicide of primisulfuron, was prepared from 2-chlorobenzoic acid through nucleophilic substitution, esterification and oxidation reaction. The structures of the target compound and intermediates were characterized through IR spectra, ^1H NMR spectra and ^13C NMR spectra, The melting points which were determined on Thiele apparatus and uncorrected reported in this paper.
