ABSTRACT The invention provides herbicidally-active sulphonates of the formula Image (I) wherein X represents a group -CHR3-OR4 andY represents a group -OR5, or X and Y together represent a group -CHR3-O- or a group -CHR3-O-Z-O-, the free oxygen atom of which is attached to the benzene ring; R1, R2 and R3, which may be the same or different, each represent hydrogen or C 1 to 6 alkkyl, or R1 and R2 together or R2 and R3 together form a C 3 to 6 alkylene chain; R4 and R5, which may be the same or different, each represent hydrogen, C 1 to 6 alkyl, C 2 to 6malkenyl, C 2 to 6 alkynyl, phenyl, a group -C(-O)R10 or a group -SO2R11; R6, R7 and R8, which may be the same or different, each represent hydrogen, C 1 to 6 alkyl, halogen, cyano, C 2 to 6 carboxylic acyl, or C1 to 4 alkoxy; R9 represents C 1 to ^ alkyl, phenyl or C 7 to 10 phenylalkyl (each of which may be unsubstituted or substituted by one or more chlorine or bromine atoms, C 1 to 4 alkyl groups, C 1 to 4 alkoxy groups or nitro groups), C 5 to 7 cycloalkyl, C 1 to 4 alkylamino, or dialkylamino wherein each alkyl moeity has from 1 to 4 carbon atoms; R10 represents C1 to 6 alkyl or alkoxy, C 2 to 6 alkenyl or alkenyloxy, C2 to 6 alkynyl or alkynyloxy, phenyl, phenoxy, phenylamino, C 1 to 6 alkylamino or dialkylamino wherein each alkyl moiety has from 1 to 6 carbon atoms, each of the groups which R10 may represent being unsubstituted or substituted by one or more halogen atoms or C 1 to 4 alkoxy groups; RA11 represents C 1 to 6 alkyl, phenyl, C 1 to 6 alkylamino or dialylamino each of the alkyl moieties thereof having from 1 to 6 carbon atoms, each if the groups which R11 may represent being unsubstituted or substituted by one or more halogen atoms or C 1 to 4 alkoxy groups; Z represents a group of formula -S(-O)n, -CR12R13 or -P(-Q)(OR14)-; n represents 1 or 2; R12 and R13, which may be the same or different, each represent hydrogen, C 1 to 6 alkyl or alkoxy, C 2 to 6 alkenyl or alkynyl, phenyl, phenoxy cyano or (C 1 to 6 alkoxy)carbonyl, or R12 and R13 together represent an oxygen atom, a sulphur atom, a C 3 to 6 alkylene chain or a C1 to 6 alkylimino group or a phenylimino group, and R14 represents C 1 to 6 alkyl; and Q represents oxygen or sulpher, together with processes for their preparation and herbicidal compositions containing them.
