| 简介 |
FIELD : organic chemistry, chemical technology.SUBSTANCE : invention relates to a method for synthesis of arylchlorosulfonyl benzamides used in synthesis of different derivatives of sulfoacids. Invention describes a method for synthesis of different arylchlorosulfonyl benzamides wherein benzoic acids are sulfochlorinated with chlorosulfonic acid, amidated with ammonia or other amine successively and prepared sulfamides are subjected for interaction with chlorosulfonic acid by the reaction of intramolecular re-amidation. Proposed method provides synthesis of arylchlorosulfonyl benzamides with aliphatic amine fragments and electron-acceptor substitutes in aromatic ring by the simplified technology.EFFECT : improved and simplified method of synthesis.4 ex |
