A herbicidal compound of the formula: ##STR24## in which Ar is ##STR25## R is chlorine, cyano, or nitro; R.sup.1 is a group --C(O)CR.sup.11 R.sup.12 --O--R.sup.13 in which R.sup.11 and R.sup.12 are independently hydrogen, or alyl, and R.sup.13 is hydrogen, alkylcarbonyl, phenylcarbonyl, phenylmethyl, or alkylaminosulfonyl;
- R.sup.2 is hydrogen, alkyl, alkylcarbonyl, alkoxycarbonyl, or a group --C(O)CR.sup.11 R.sup.12 --O--R.sup.13 ;
- R.sup.8 is halogen;
- R.sup.9 is haloalkyl;
- R.sup.10 is hydrogen, halogen, or a group --NR.sup.14 R.sup.15 in which R.sup.14 is hydrogen or alkyl; R.sup.15 is alkyl, alkynyl, or a group --CHR.sup.16 --Ar.sup.1 in which R.sup.16 is hydrogen or alkyl; and Ar.sup.1 is tetrahydrofuran-2-yl; furan-2-yl, thien-2-yl, phenyl, or phenyl substituted with halogen or alkoxy, and
- when R.sup.10 is a group --NR.sup.14 R.sup.15, in addition to the substituents listed above, R.sup.1 may be alkylcarbonyl, haloalkylcarbonyl, or cycloalkylcarbonyl; and R.sup.2 may be hydrogen, alkylcarbonyl, or cycloalkylcarbonyl;
- wherein each alkyl and alkoxy contains 1 to 4 carbon atoms, each cycloalkyl contains 3-6 carbon atoms, and each alkynyl contains 3-4 carbon atoms
- with the proviso that when R is chlorine or nitro, R.sup.13 is alkylcarbonyl, phenylcarbonyl, or alkylaminosulfonyl.
- 2. A compound of claim 1 in which R is cyano or nitro, and halogen is chlorine or fluorine.
- 3. A compound of claim 2 in which r is substituted pyridin-2-yl, R is cyano, R.sup.1 is --C(O)CR.sup.11 R.sup.12 --O--R.sup.13 or alkylcarbonyl, R.sup.11 and R.sup.12 are hydrogen, R.sup.13 is alkylcarbonyl, R.sup.2 is hydrogen or alkylcarbonyl, and R.sup.10 is hydrogen.
- 4. A compound of claim 3 in which R.sup.13 is acetyl, R.sup.2 is hydrogen or acetyl, R.sub.8 is chlorine, and R.sub.9 is trifluoromethyl.
- 5. A compound of claim 4 in which R.sup.13 and R.sup.2 are acetyl.
- 6. An herbicidal composition comprising an herbicidally effective amount of a compound of claim 1 in admixture with a suitable carrier.
- 7. A method for controlling undesired plant growth which comprises applying to the locus where control is desired an herbicidally effective amount of the composition of claim 5.
