Abstract

Abstract Disclosed are compounds such as 3-[5-(1,1-dimethylethyl)-3-isoxazolyl]-1-methyl-4-hydroxy-2-imidazolidinone; their control of weeds such as johnsongrass; the process of making them; and intermediates for making them, the compounds being represented by a Formula I: ##STR1## wherein A is ##STR2## where R is an alkyl of up to six carbon atoms; an alkenyl of up to five carbon atoms; an alkynyl of up to five carbon atoms; a cycloalkyl selected from the group consisting of cyclopropyl, cyclobutyl, cyclopentyl, and cyclohexyl; a haloalkyl of up to six carbon atoms; --R 4 --O--R 5 , or --R 4 --S--R 5 , where R 4 is an alkylene of up to six carbon atoms and R 5 is an alkyl of up to six carbon atoms; ##STR3## where Z is nitro (NO 2 ), chloro (Cl), bromo (Br), fluoro (F), or R 5 , and n is 0, 1, 2, or 3; R 1 is an alkyl of up to three carbon atoms, or allyl; R 2 is hydroxy (OH), chloro (Cl) or bromo (Br); and R 3 is hydrogen (H), an alkyl of up to four carbon atoms, allyl, or hydroxy (OH).
