Sulfonamide derivatives of the formula
wherein J is phenyl fused to a specified carbocyclic or heterocyclic ring, said phenyl and said ring both being optionally substituted;
R is H or CH3;
W is 0 or S;
A is substituted monocylic or bicyclic heterocyclic group;
and their agriculturally suitable salts, exhibit herbicidal and plant growth regulant activities. They may be formulated for agricultural use in conventional manner.
The novel compounds may be made in various ways. e.g. by reacting a novel sulfonylisocyanate or sulfonylisothiocyanate of formula JSO2NCW with an appropriate heterocyclic amine of formula RHNA.
式中的磺酰胺衍生物
其中 J 是与特定碳环或杂环融合的苯基,所述苯基和所述环均被任选取代;
R 是 H 或 CH3
W 是 0 或 S;
A 是被取代的单环或双环杂环基团;
及其农用盐类具有除草和植物生长调节活性。它们可按常规方法配制成农用制剂。
这些新型化合物可以通过多种方法制得,例如,将式 JSO2NCW 的新型磺酰基异氰酸酯或磺酰基异硫氰酸酯与适当的式 RHNA 的杂环胺反应。
