摘要:
1-Alkyl-4-benzoyl-5-hydroxy-1H-pyrazole compounds in which the benzoyl moiety is substituted in the 2-position with groups such as halo or alkyl, in the 4-position with an alkylsulfonyl group, and in the 3-position with an acyclic or cyclic derivatized amino group, such as 1-ethyl-4-(2-chloro-4-methylsulfonyl-3-(morpholin-4-yl)benzoyl-5-hydroxy-1H-pyrazole, were prepared and found to be useful for the control of a variety of broadleaf and grassy weeds. The compounds can be applied either preemergently or postemergently and can be used to control undesirable vegetation in corn, rice, and wheat crops.

1-Alkyl-4-benzoyl-5-hydroxy-1H-pyrazole compounds in which the benzoyl moiety is substituted in the 2-position with groups such as halo or alkyl, in the 4-position with an alkylsulfonyl group, and in the 3-position with a 3-oxetanyloxy or an oxetanylmethoxy substituent were prepared and found to be useful for the control of a variety of broadleaf and grassy weeds. The compounds have favorable environmental and toxicological properties and can be used to control undesirable vegetation in crops.

1-Alkyl-4-benzoyl-5-hydroxypyrazole compounds in which the benzoyl moiety is substituted in the 2-position with a halo, alkyl, or alkoxy group, in the 4-position with an alkylsulfonyl group, and in the 3-position with an optionally substituted phenyl group, for example, 1-(1,1-dimethylethyl)-4-(2-methyl-4-methyl-sulfonyl-3-(4-methoxyphenyl)benzoyl-5-hydroxypyrazole, were prepared and found to be useful for the control of a variety of broadleaf and grassy weeds. The compounds can be applied either preemergently or postemergently and can be used to control undesirable vegetation selectively in small grain crops and turf or non-selectively.

摘要:
4-Substituted 5-polycyclylpyrimidine compounds in which the 5-substituent is polycyclic and is attached to the pyrimidine moiety through an aliphatic carbon atom, such as 5-(2,2-dimethylindan-1-yl)-4-methylthiopyrimidine, were prepared and found to possess excellent herbicidal activity. The compounds are especially useful for the control of undesirable vegetation in paddy rice.
