Abstract
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.
