Abstract: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. |
Key words:2-methoxycarbonylphenylsulphonic chloride;primisulfuron;synthesis;2-chlorobenzoic acid |
