2-Chlorobenzenesulfonyl isocyanate Usage And Synthesis
Uses2-Chlorobenzenesulfonyl isocyanate may be used in the synthesis of N-thiazolyl-N′-(2-chlorobenzenesulfonyl)urea derivatives and N-(2-chlorophenylsulfonyl)-N′-(4-methoxy-6-methyl-triazin-2-yl)urea.
General Description2-Chlorobenzenesulfonyl isocyanate is an aryl isocyanate that can be synthesized by the catalytic carbonylation of potassium N,2- dichlorobenzenesulfonamidate in acetonitrile. The C-acylation of nitrogen bearing heterocycles using 2-chlorobenzenesulfonyl isocyanate has been reported.
