This invention relates to herbicidal N-(heterocyclylcarbonyl)sulfonamide compounds, compositions comprising N-(heterocyclylcarbonyl)sulfonamide herbicides and an agronomically acceptable carrier, and the use thereof as broad spectrum herbicides which are effective against both monocot and dicot weed species in both preemergence and postemergence applications. This invention also teaches methods of preparing these compounds as well as methods of using the compounds as herbicides.

N-(heterocyclylcarbonyl)sulfonamide herbicides

This invention describes a new and convenient single step process for preparing 2-aryl-3-substituted-4(3H)-pyrimidinone herbicides by reacting a N-substituted amidine (or its hydrohalide salt) with a .beta.-keto ester under conditions of high pressure. The 2-aryl-3-substituted pyrimidinone compounds produced by the process of the present invention are very useful as herbicidal agents for the control of weeds in agronomically important crops.

High pressure process to produce 2-aryl-3-substituted pyrimidione

This invention relates to a process for the preparation of pyrimidinone compounds of the formula ##STR1## wherein Ar is an optionally substituted aryl or heteroaromatic moiety,

Process for pyrimidinone compounds

The present invention relates to compositions, having herbicidal synergistic effects, comprising

Various synergistic herbicidal compositions

Disclosed are herbicidal aryl substituted cycloalkyl and aryl substituted cycloalkenyl compounds, herbicidal compositions, and herbicidal use of the compounds and compositions. The aryl substituent is selected from substituted phenyl, unsubstituted or substituted five-membered heterocycle, and unsubstituted or substituted six-membered heterocycle.

Aryl-substituted cycloalkanes and cycloalkenes and herbicidal use thereof

Disclosed are herbicidal halopyridyl triazolinones, herbicidal compositions comprising the halopyridyl triazolinones, and herbicidal use of the compounds and compositions. Such compounds and compositions are useful as both preemergence and postemergence herbicides in a variety of crops.

Halopyridyl triazolinone herbicides and herbicidal use thereof

A class of 2-arylpyrimidines which is useful in the control of weeds of the general formula: ##STR1## wherein R.sup.2 is an optionally substituted aromatic ring; R.sup.3 is a saturated or unsaturated alkyl group; R.sup.5 is selected from acyl, alkoxyalkyl, alkoxyimino, dialkoxyalkyl, formyl, hydroxyalkyl, alkoxyalkoxy, cyanoalkyl and hydroxyimino; R.sup.6 is selected from hydrogen, halo, alkyl, haloalkyl, aryl, and alkoxy; and X is oxygen or sulfur.

2-arylpyrimidines and herbicidal use thereof

A class of 5-aryl-isoxazolinones and compositions thereof which are useful in the control of weeds is of the general formula ##STR1## wherein Ar is a substituted or unsubstituted aryl or heteroaryl;

5-aryl-isoxazolinones and herbicidal use thereof

This invention relates to glutarimide compounds exhibiting herbicidal activity having the structure ##STR1## wherein A is carbonyl, thiocarbonyl or methylene, A.sup.1 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.

Herbicidal glutarimides

A class of 2-aryl-5,6-dihydropyrimidinones and compositions thereof which are useful in the control of weeds is of the general formula ##STR1## wherein Ar is a substituted or unsubstituted aryl or heteroaryl;

2-aryl-5,6-dihydropyrimidinones and herbicidal use thereof

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.

A class of 2-arylpyrimidines which is useful in the control of weeds of the general formula: ##STR1## wherein R.sup.2 is an optionally substituted aromatic ring; R.sup.3 is a saturated or unsaturated alkyl group; R.sup.5 is selected from acyl, alkoxyalkyl, alkoxyimino, dialkoxyalkyl, formyl, hydroxyalkyl, and hydroxyimino; R.sup.6 is selected from hydrogen, halo, alkyl, haloalkyl, aryl, and alkoxy; and X is oxygen or sulfur.

A class of 2-aryl-5,6-ring-fused pyrimidines which is useful in the control of weeds is of the general formula: ##STR1## wherein Ar is an optionally substituted aromatic or heteroaromatic ring; R.sup.3 is an alkynyl or alkoxyalkyl group, --R.sup.5 ----R.sup.6 -- is a fused ring moiety bonded to the pyrimidine ring at the 5 and 6 positions; and X is oxygen or sulfur.
