ABSTRACT PP 35615 "Heterocyclic Compounds" A herbicidal compound of formula (I) : Image (I) in which Ar is an optionally subsitituted aryl or heterocyclic ring system; R1 and R2 are independently selected from H, optionally substituted alkyl, alkenyl or alkynyl, halogen, NRaRb, or R1 and R2 together with the carbon to which they are attached form an optionally substituted alkenyl or cycloalkyl group; R3 is CO2R4, CN, COR4, CH2OR4, CH(OH)R4, CH(OR4)R5, CH2OSO2R4, CH2OSO3R4, CH2ONR6R7, CSNH2, COSR4, CSOR4, CONHSO2R4, CONR6R7, CONHNR6R7, CONHN+R6R7R8 Y-, CO2-M+ or COON=CR6R7; M+ is an agriculturally acceptable cation; Y- is an agriculturally acceptable anion; R4, and R5 are independently selected from H or an optionally substituted alkyl, aryl, alkenyl or alkynyl group; R6, R7, R8, R9, Ra and Rb are independently selected from H or an optionally substituted alkyl, alkenyl, aryl or alkynyl group or any two of R6, R7, R8, R9, Ra and Rb together with the atom to which they are attached form a cycloalkyl or heterocyclic ring; R6 and R7 may also be a heterocyclic ring; W is O or NR10 where R10 is H or lower alkyl; X is (CH2)n, CH=CH, CH(ORc)CH2, COCH2; where Rc is H or an optionally substituted alkyl, aryl, alkynyl or alkynyl group; and n is 0, 1 or 2. Process for the preparation of these compounds and compositions containing them are also described.
