摘要

FIELD: organic chemistry, chemical technology. SUBSTANCE: product: derivatives of sulfonylamino(thio)carbonyl of the general formula (I)where Q, Rand Rhave values indicated in claim 1 of invention and synthesized by method indicated in claim 2. Also, the proposed herbicide agent has at least one carrier and an active substance, derivative of sulfonylamino(thio)carbonyl of the formula (I) indicated above. Agent is prepared by mixing an active substance with at least one carrier. Derivative of sulfonylamino(thio)carbonyl of the formula indicated above (I) can be used for struggle against weeds by treatment of weeds or soil with derivatives of sulfonylamino(thio)carbonyl. EFFECT: improved method of synthesis, enhanced effectiveness.
