Abstract
Novel herbicides of the formula ##STR1## in which R1 represents alkyl,
R2 represents hydrogen, alkyl, alkylcarbonyl, alkoxycarbonyl, alkylsulphonyl, alkenyl, alkinyl or optionally substituted aralkyl, and
R3 represents optionally substituted aryl.
Intermediates of the formula ##STR2## in which R6 is hydrogen, chlorine or hydroxyl,
are also new.
