Preparation of sulfonamides

摘要

Sulfonamides are prepared by reacting ammonia or an amine with a halosilane and then reacting the resulting silylamine with sulfuryl chloride in the presence of a solvent which is inert under the reaction conditions. The sulfonamides are used as intermediates for drugs and crop protection agents, and are starting materials for the preparation of alkylamidosulfonyl chlorides.
