This invention pertains to phosphosulfonates, having the general formula ##STR1## wherein Y is phenyl, naphthyl, benzyl, a (C.sub.5 -C.sub.8)cycloalkyl, a 5-membered heteroaromatic ring, a 6-membered heteraromatic ring, a fused 5,6-membered heteroaromatic ring, or a fused 6,6-membered heteroaromatic ring; and X is oxygen or sulfur; and R.sup.1 and R.sup.2 are each independently selected from substituted or unsubstituted alkyl, alkoxy, alkylthio, alkenyloxy, alkynyloxy, haloalkoxy, cyanoalkoxy, alkoxyalkoxy, cycloalkyloxy, cycloalkylalkoxy, alkylideneiminooxy, chloro, amino, phenyl or phenoxy; or R.sup.1 and R.sup.2 are both alkoxy, taken together with the phosphorus atom to form a 6-membered oxygen-containing ring; compositions containing these compounds and their use as herbicides.
这项发明涉及磷磺酸酯,其一般公式为##STR1##其中Y为苯基、萘基、苄基、(C.sub.5 -C.sub.8)环烷基、5-成员杂芳环、6-成员杂芳环、融合的5,6-成员杂芳环或融合的6,6-成员杂芳环;X为氧或硫;R.sup.1和R.sup.2各自独立地选自取代或未取代的烷基、烷氧基、烷硫基、烯氧基、炔氧基、卤代烷氧基、氰基烷氧基、烷氧基烷氧基、环烷氧基、环烷基烷氧基、烷基亚胺氧基、氯、氨基、苯基或苯氧基;或R.sup.1和R.sup.2均为烷氧基,与磷原子一起形成一个6-成员含氧环;含有这些化合物的组合物及其用作除草剂。
