| Abstract: | 2-Chloro-benzensulfonyl isocyanate and methyl 2- (sulfonyl- isocyanatc) benzoate are two of the main intcrmcdiacs for synthesis of super high active sulfonyl urea herbicides. The synthetic method that this paper reports dcalcd with diazotisation to 2-chloro-anilinc followed by chlorosulfonation, animation or hydrolysis to saccharin followed by methyl esterification, then reaction with oxalyl chloride to produce relative phcnylsulfonyl isocyanate, and simplified the method reported by literature. |
