The invention discloses compounds of formula I ##STR1## wherein X is oxygen or sulfur,

2-phenyl-7-chloro-perhydroimidazo[1,5A]pyridines

This invention relates to novel 2-(2,4,5-substituted phenyl) hydantoin compounds, intermediates therefor, synthesis thereof, and the use of said compounds for combatting weeds.

Hydantoin compounds

This invention described in this patent application relates to novel amides of the formula (I) ##STR1## wherein the substituents are as defined in the disclosure, intermediates for such amides, synthesis thereof and their use for the control of weeds.

Amides

Arylaminocarbonyl compounds of the formula (I) ##STR1## wherein R.sub.2-6, X.sub.1, A and m are as defined in the disclosure, intermediates therefore, synthesis thereof, and the use of said compounds for the control of weeds are described.

Arylaminocarbonyl compounds

The invention provides 5-membered heteroaromatic compounds of formula I

Herbicidal N-thienyl-chloroacetamides

The invention provides novel pyrimidine compounds substituted in the 5-position by a chloroacetylamino group which are useful as herbicides. Other objects of the invention are herbicidal compositions comprising such novel compounds and methods of combatting weeds with the aid of said novel compounds.

Novel N-(5-pyrimidinyl)-chloroacetamides

The invention provides 6-(2-propenyloxy)-4-methyl-2-aminopyrimidine derivatives which are chlorinated or brominated in 2 or 3 position of the 2-propenyl moiety, e.g. 6-(2-chloro-2-propenyloxy)-4-methyl-2-n-hexylaminopyrimidine. The compounds are useful as herbicides and allow the control of undesired weeds in a crop locus.

Pyrimidine derivatives and their use as herbicides

Pyrimidines having an amino group in the 2-position and a cyclopropylmethoxy group in the 4-position of the pyrimidine nucleus. Compounds according to the invention have valuable herbicidal activity, particularly after pre-emergence application in cotton and sunflower.

Novel pyrimidinyl ethers, their use as herbicides, herbicidal

The present invention concerns novel pyrimidinyl phosphoric and thiophosphoric esters. ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are substituents, e.g. alkyl,

Pesticidal pyrimidinyl phosphorus esters

The present invention concerns novel 4-hydroxypyrimidine derivatives of the formula: ##SPC1## Wherein R.sub.1 is a substituent, e.g., alkyl, R.sub.2 is hydrogen or a substituent, e.g., alkyl R.sub.3 is amino unsubstituted or substituted by alkyl, a nitrogen heterocycle, alkoxy or alkylthio, which are used as intermediates in the production of useful insecticides.
