Abstract
This invention relates to glutarimide compounds exhibiting herbicidal activity having the structure ##STR1## wherein A is carbonyl, thiocarbonyl or methylene, Al is carbonyl or methylene, Q is O or (CH.sub.2).sub.n where n is 0 or 1, D is CH or N and R, R.sup.1, R.sup.2, T, X, Y and Z are as defined within, compositions containing these compounds and methods of using these compounds as herbicides and algicides.
Claims20
A herbicidal compound of the formula ##STR60## wherein A is carbonyl, thiocarbonyl or methylene;
- A.sup.1 is carbonyl or methylene;
- Q is (CH.sub.2).sub.n, where n is 0 or 1, or oxygen;
- R is (C.sub.1 -C.sub.4)alkyl, (C.sub.1 -C.sub.4)haloalkyl containing from one to nine halo atoms, or phenyl;
- R.sup.1 is hydrogen or (C.sub.1 -C.sub.2)alkyl;
- R.sup.2 is hydrogen;
- or
- R, R.sup.1 and R.sup.2 taken together form a fused phenyl ring;
- X is hydrogen, cyano or halogen;
- T is hydrogen or fluorine;
- and
- Z and Y together form a 6-membered heterocyclic ring fused to the phenyl ring structure to form a bicyclic moiety having the structure ##STR61## wherein L is oxygen
- R.sup.3 is hydrogen or alkyl;
- R.sup.4 is hydrogen;
- alkyl;
- alkenyl;
- alkynyl;
- alkoxyalkyl;
- alkenyloxyalkyl;
- alkynyloxyalkyl;
- alkoxycarbonylalkyl;
- cycloalkyl;
- cycloalkylalkyl;
