The invention herein relates to titled compounds having the structure ##STR1## wherein the R.sub.1 -(R.sub.4).sub.n members are as defined in the claims. Characteristic features of these compounds are the haloalkyl R.sub.2 radical and cyclization of two R.sub.4 members at the meta and para positions of the phenyl ring to form a substituted benzoxazinone ring fused to the phenyl or benzthiazinone ring. Such compounds are useful as active ingredients in herbicidal compositions to control undesirable weeds in various crops.
本发明涉及具有以下结构的化合物,其中R.sub.1 -(R.sub.4).sub.n成员如索引中所定义。这些化合物的特征是卤代烷基R.sub.2基团和两个R.sub.4成员在苯环的间位和对位发生环化,形成与苯环或苯并噻唑酮环融合的取代苯并噻唑酮环。这些化合物可用作除草剂组合物中的活性成分,用于控制各种作物中的不良杂草。
