摘要：
Compounds of the formula:
ARE OUTSTANDINGLY EFFECTIVE HERBICIDES PARTICULARLY WHEN USED AS SELECTIVE HERBICIDES AND ARE OUTSTANDINGLY TOLERATED BY CROP PLANTS.
IN WHICH R and R4 are, e.g., optionally substituted aliphatic hydrocarbyl; R1, R2, and R3 represent hydrogen, alkyl, cycloalkyl, alkoxy, haloalkyl and/or halogen; Furthermore R2 and R3 conjointly may represent a -(CH)4grouping to form a fused benzene ring with the adjacent atoms of the phenyl ring shown in the formula X is sulfur; Y is oxygen, sulfur or a group of the formula
