The present invention is directed to compounds of the formula ##STR1## wherein R.sup.1 is C.sub.1 -C.sub.6 alkyl, C.sub.5 -C.sub.6 cycloalkyl, ##STR2## each of R.sup.2 and R.sup.3 is taken separately and is independently hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.3 -C.sub.4 alkenyl, C.sub.3 -C.sub.4 alkynyl, C.sub.3 -C.sub.4 cycloalkyl or C.sub.1 -C.sub.3 alkoxy, or R.sup.2 and R.sup.3 are taken together with the nitrogen atom to which they are attached and form piperidine, morpholine or pyrrolidine; each R.sup.4 independently is halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -Cphd 4 alkoxy, C.sub.1 -C.sub.4 haloalkyl, C.sub.1 -C.sub.4 haloalkoxy or cyano; X is 0 or S; and m is 0-3; with the provisos that when R.sup.4 is C.sub.1 -C.sub.4 alkyl, that substituent exists at other than the 2 or 6 position of the phenyl ring; and when R.sup.2 is C.sub.1 -C.sub.3 alkoxy, R.sup.3 is other than C.sub.1 -C.sub.3 alkoxy. These compounds exhibit activity as terrestrial herbicides, aquatic herbicides, and aquatic algicides.
本发明涉及以下结构的化合物 ##STR1## 其中 R.sup.1 是 C.sub.1 -C.sub.6 烷基,C.sub.5 -C.sub.6 环烷基,##STR2## R.sup.2 和 R.sup.3 中的每一个单独取且独立地是氢,C.sub.1 -C.sub.4 烷基,C.sub.3 -C.sub.4 烯基,C.sub.3 -C.sub.4 炔基,C.sub.3 -C.sub.4 环烷基或 C.sub.1 -C.sub.3 烷氧基,或者 R.sup.2 和 R.sup.3 与它们连接的氮原子一起形成哌啶,吗啉或吡咯啉;每个 R.sup.4 独立地是卤素,C.sub.1 -C.sub.4 烷基,C.sub.1 -C.sub.4 烷氧基,C.sub.1 -C.sub.4 卤代烷基,C.sub.1 -C.sub.4 卤代烷氧基或氰基;X 是 0 或 S;m 是 0-3;但是当 R.sup.4 是 C.sub.1 -C.sub.4 烷基时,该取代基存在于苯环的 2 或 6 位置之外;当 R.sup.2 是 C.sub.1 -C.sub.3 烷氧基时,R.sup.3 不是 C.sub.1 -C.sub.3 烷氧基。这些化合物表现出作为陆生除草剂、水生除草剂和水生杀藻剂的活性。
