- 7. The compound of claim 6 selected from the group consisting of ethyl-3-(5-(2-chloro-4-(trifluoromethyl)-phenoxy)-2-nitro-phenylamino)propionate; methyl-3-(5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-nitro-phenylamino)-propionate; and methyl-3-(5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-nitro-phenylamino)butyrate.
- 8. The compound of claim 7 which is ethyl-3-(5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-nitro-phenylamino)-propionate.
- 9. The compound of claim 7 which is methyl-3-(5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-nitro-phenylamino)butyrate.
- 10. A compound of the formula: ##STR7## wherein R.sup.1 is a (C.sub.4 -C.sub.5)alkylene optionally substituted with additional methyl groups of up to one per carbon atom of the alkylene group; and R.sup.2 is a carb(C.sub.1 -C.sub.2)alkoxy or a carboxy group or an agronomically acceptable salt thereof.
- 11. The compound of claim 10 wherein the (C.sub.4 -C.sub.5)-alkylene of R.sup.1 is substituted with at least one methyl group and is optionally substituted with additional methyl groups of up to one per carbon atom of the alkylene group.
- 12. The compound of claim 11 which is methyl-6-(5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-nitro-phenylamino)-hexanoate.
- 13. A herbicidal composition comprising a herbicidally effective amount of the compound of claim 1 and an agronomically acceptable carrier.
