摘要：
A herbicidal compound of formula (I):
wherein X is O, S(O) n or NR a where R a is H or alkyl and n is O, 1 or 2;
R¹ is H or halo;
R² is N or CR³ where R³ is halo or NO₂;
R⁴ is H, halo, NO₂, alkyl, haloalkyl, CN, CO₂alkyl, cycloalkyl, phenyl, COalkyl, COphenyl, CHO,OH, NH₂, NHCOalkyl or alkoxy
R⁵ is H, halo or optionally substituted alkyl;
R⁶ is H, halo or optionally substituted alkyl;
provided that at least one of R⁵ and R⁶ is halo;
R⁷ is CN, CHO, COOR⁸, CONR⁸R⁹, where R⁸ is H, optionally substituted alkyl, alkenyl, alkynyl or aryl and R⁹ is a group R⁸, SO₂alkyl, NR¹⁰R¹¹ or N⁺R¹⁰R¹¹R¹² Z⁻ where Z is an agriculturally acceptable anion e.g. chloride and R¹⁰, R¹¹ and R¹² are independently selected from hydrogen and alkyl. Processes for the preparation of these compounds and compositions containing them are also described.
