Abstract

FIELD: organic chemistry. SUBSTANCE: desired compounds having common formula $$$ (where $$$ is Cl, $$$ and $$$ is H, Cl) are prepared by phosgenation of benzenesulfamides having common formula $$$ (where $$$ and $$$ are as mentioned above). The process is carried out in the presence of catalyst and additive which contains isocyanate in the medium of chlorine-containing solvent. Tetramethyl ethylene diamine is used as mentioned above catalyst, phenylisocyanate being used as said additive. EFFECT: increases yield of desired product.
