摘要
Novel compounds are provided which exhibit activity as herbicides for combating weeds. The novel compounds have the formula: …CHEM… wherein X is hydrogen, halo, trihalomethyl, alkyl; nitro or cyano; Y is hydrogen or halo; Z is halo, trihalomethyl or pentahaloethyl, W is nitro, cyano, halo or a radical of the formula S(O))n min R wherein R is (C1-C6)alkyl or trihaloalkyl, n min is 0, 1 or 2; R1 is hydrogen or an optionally substituted saturated or unsaturated hydrocarbyl radical; R2 is hydrogen or (C1-C6)alkyl; n is 0, 1, 2 or 3; R3 is an optionally substituted group which is alkoxycarbonyl, alkylcarbonyl, formyl aminocarbonyl, mononuclear aryloxy or carboxy (including agronomically acceptable amides, esters or salts thereof); or R1 and R2 may be joined to form, together with the nitrogen to which they are attached, a heterocyclic ring containing one nitrogen atom and from 4 to 8 nuclear carbon atoms.
