Sulfonamide derivatives of the formula
wherein
W is 0 or S;
R is H or CH3;
J is a phenyl, thienyl, pyrazolyl or pyridyl group, each substituted by a tetrazolyl moiety;
A is mono- or bicyclic heterocyclic group, e.g. pyrimidinyl or triazinyl;
and their agriculturally suitable salts, exhibit potent therbicidal activity. Some also show a plant growth regulant effect.
The novel compounds may be made e.g. by reacting a sulfonyl isocyanate or sulfonyl isothiocyanate JNCW with an appropriate heterocyclic amine HNR.A.
式中的磺酰胺衍生物
其中
W 是 0 或 S
R 是 H 或 CH3
J 是苯基、噻吩基、吡唑基或吡啶基,每个基团都被四唑基取代;
A 是单环或双环杂环基团,如嘧啶基或三嗪基;
以及它们在农业上适用的盐类,具有很强的杀虫活性。有些化合物还具有植物生长调节作用。
这些新型化合物可以通过磺酰基异氰酸酯或磺酰基异硫氰酸酯 JNCW 与适当的杂环胺 HNR.A. 反应制成。
