Abstract

Opticalls active enantiomers of the formula I ##STR1## where R is a group of the formulae ##STR2## R.sub.1 and R.sub.2, among others, are halogen or CF.sub.3 and Z is a carboxyl, carboxylate, carboxylic acid ester, thioester, carbonamide, carboxylic acid anilide, carbohydrazide or thioamide group, are interesting herbicides the effect of which is considerably superior to that of the optically inactive racemates.
