    摘要: Compounds having the formula ##STR1## in which: R is C.sub.1 -C.sub.8 alkyl; or phenyl optionally substituted by 1 or 2 groups selected from C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 haloalkoxy, nitro or halo;R.sub.1 is C.sub.1 -C.sub.4 alkyl or phenyl;R.sub.2 is C.sub.1 -C.sub.4 alkyl;R.sub.3 is C.sub.2 -C.sub.4 alkyl or allyl; andX is oxygen, sulfur or NR.sub.4 where R.sub.4 is hydrogen or C.sub.3 -C.sub.4 alkyl;provided that(i) if R.sub.1 is methyl, R is phenyl or substituted phenyl and(ii) if R.sub.3 is isopropyl, X is NR.sub.4, and R.sub.1 is alkyl; and their agriculturally acceptable salts are herbicides.
