Abstract

Abstract Compounds of the formula ##STR1## wherein R 1 and R 2 are each hydrogen, chlorine or fluorine; and R 3 is --CH 2 OH, --CH 2 --O--COR 4 , --CH 2 --O--CONHR 5 , --COOH, --COOCat, --COOR 6 , --CONR 7 R 8 or --CO--SR 9 ; where Cat is one equivalent of an inorganic or organic cation; R 4 is hydrogen or alkyl of 1 to 10 carbon atoms; R 5 is alkyl of 1 to 4 carbon atoms, phenyl or halo-substituted phenyl; R 6 is alkyl of 1 to 10 carbon atoms which may optionally have a chloro, hydroxyl, lower alkoxy, lower alkoxy-lower alkoxy, lower alkylthio, amino, mono-lower alkyl-amino, di-lower alkyl-amino, allyloxy or phenoxy substituent attached thereto; phenyl; benzyl; monochloro-benzyl; dichloro-benzyl; cyclohexyl; 1-ethynyl-cyclohexyl; lower alkenyl; lower alkynyl; --N═C(CH 3 ) 2 ; 2--(2',4',5'-trichloro-phenoxy)-ethyl, 2-(2', 5'-dichloro-4'-bromo-phenoxy)-ethyl; or ##STR2## R 7 is hydrogen, lower alkyl, hydroxy-lower alkyl, lower alkenyl, lower alkynyl, phenyl, chloro-substituted phenyl, hydroxyl, amino, phenyl-amino or thiazolyl; R 8 is hydrogen, lower alkyl, lower alkenyl or hydroxy-lower alkyl; R 9 is hydrogen or alkyl of 1 to 10 carbon atoms; and N is an integer from 2 to 6, inclusive. The compounds are useful as herbicides.
