ABSTRACT:
Herbicides having the formula ##STR1## in which X is oxygen or sulfur; and if X is sulfur, R.sub.1 is C.sub.1 -C.sub.6 alkyl, C.sub.5 -C.sub.6 cycloalkyl, allyl, phenyl, tolyl, chlorophenyl, 3,4-dichlorophenyl, or phen-(C.sub.1 -C.sub.2)alkyl; R.sub.2 is C.sub.1 -C.sub.4 alkyl, C.sub.2 -C.sub.4 alkoxyalkyl, or allyl; R.sub.3 is C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxyalkyl, pyridyl, phenyl or substituted phenyl in which the substituents are halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 haloalkoxy, nitro and/or cyano; or R.sub.2 and R.sub.3 taken together form an alkylene chain having from 2 to 6 carbon atoms optionally substituted by up to two C.sub.1 -C.sub.4 alkyl groups; if R.sub.3 is alkyl or alkoxyalkyl, then R.sub.4 and R.sub.5 are each C.sub.2 -C.sub.4 alkyl; if R.sub.3 is phenyl, substituted phenyl or pyridyl, then R.sub.4 and R.sub.5 are C.sub.2 -C.sub. 6 alkyl, phenyl or substituted phenyl; or R.sub.3 and R.sub.5 taken together form an alkylene chain having from 2 to 5 carbon atoms and R.sub.4 is C.sub.2 -C.sub.4 alkyl;
and if X is oxygen, R.sub.1 and R.sub.4 taken together form an alkylene ring having from 2 to 5 carbon atoms and R.sub.2, R.sub.3 and R.sub.5 are each C.sub.2 -C.sub.4 alkyl; provided that R.sub.3 is not 2,3,6-trifluorophenyl are described.
