Novel sulfonamide derivatives of the formula
wherein J is
where E is a bridge of 3 or 4 atoms including 0-2 oxygen, sulfur or nitrogen heteroatoms and at least one carbon atom;
G is O, S, NH or NCH3;
W is 0 or S;
R is H or CH3; and
A is a substituted nono or bicyclic heterocyclic residue, especially a pyrimidine or triazine residue;
exhibit potent herbicidal activity; many also exhibit a plant growth regulant effect.
The novel compounds may be made by a variety of synthetic routes, e. g. by reacting the appropriate sulfonyl isocyanate or isothiocyanate of formula JS02NCW with an appropriate heterocyclic amine of formula
新型磺酰胺衍生物 式中 J 是 E 是由 3 或 4 个原子组成的桥,包括 0-2 个氧、硫或氮杂原子和至少一个碳原子; G 是 O、S、NH 或 NCH3;W 是 0 或 S;R 是 H 或 CH3;A 是取代的壬环或双环杂环残基,特别是嘧啶或三嗪残基;具有强效除草活性;许多还具有植物生长调节作用。 新型化合物可通过多种合成路线制得,例如,将式 JS02NCW 中适当的磺酰异氰酸酯或异硫氰酸酯与式 JS02NCW 中适当的杂环胺进行反应
