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, R wherein R is(C1-C6) alkyl or trihaloalkyl; n min is 0, 1 or 2; R<1> is hydrogen, halo, alkyl, mononuclear aryl, (C1-C6)alkoxy, (C1-C6)alkylthio or dialkylamino; R<2> is substituted alkyl other than CF3), trifluoromethyl, cyano, carboxy, substituted or unsubstituted alkoxy, alkoxycarbonyl, alkylcarbonyl, alkylthio, aminocarbonyl, mononuclear arylcarbonyl, mononuclear aryloxy or carboxy including agronomically acceptable amides, esters or salts of said carboxy or R<1> and R<2> may be joined together to form a ring containing from 4 to 8 nuclear carbon atoms. |
