Abstract
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-1 H-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.
Claims6
A benzoic acid compound of the formula:
- ##STR78## wherein X represents F, Cl, Br, C.sub.1 -C.sub.4 alkyl, OCH.sub.3, OC.sub.2 H.sub.5, Ch.sub.2 OCH.sub.3, or CH(CH.sub.3)OCH.sub.3 ;
- Y represents CH.sub.3, C.sub.2 H.sub.5, or CH(CH.sub.3).sub.2 ;
- and
- each R independently represents H or C.sub.1 -C.sub.4 alkyl, C.sub.3 -C.sub.4 alkenyl, or C.sub.3 -C.sub.4 alkynyl (each optionally possessing up to two substituents selected from Cl, Br, CN, C.sub.1 -C.sub.4 alkoxy, and C.sub.1 -C.sub.3 fluoroalkoxy and up to three F substituents) or benzyl (optionally possessing up to three ring substituents selected from F, Cl, Br, CN, CF.sub.3, NO.sub.2, CH.sub.3, C.sub.2 H.sub.5, OCH.sub.3, and OC.sub.2 H.sub.5);
- with the proviso that both of R do not represent H;
- or
- NR.sub.2 represents a 4- to 7-membered aliphatic nitrogen heterocyclic substituent optionally possessing O as a second ring heteroatom, optionally possessing one double bond, and optionally possessing up to three substituents selected from F, Cl, Br, CN, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.3 fluoroalkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.3 fluoroalkoxy, C.sub.1 -C.sub.3 alkoxymethyl, and phenyl (optionally possessing up to three ring substituents selected from F, Cl, Br, CN, CF.sub.3, NO.sub.2, CH.sub.3, C.sub.2 H.sub.5, OCH.sub.3, and OC.sub.2 H.sub.5);
- or
- NR.sub.2 represents a pyrrol-1-yl or pyrazol-1-yl moiety optionally possessing up to two substituents selected from F, Cl, Br, I, CN, CF.sub.3, C.sub.1 -C.sub.3 alkyl, and C.sub.1 -C.sub.3 alkoxy.
