Abstract
The present invention concerns new .alpha.-phenoxy-thiolpropionic acids and salts of the formula ##STR1## wherein R is hydrogen a metal cation or the cation of an amino- or ammonio-group, Z is a substituted phenyl or a substituted pyrid-2-yl radical. These compounds have herbicidal activity by themselves but can be used as intermediats for the synthesis of more active derivatives.
Claims8
A compound of the formula ##STR12## wherein R represents hydrogen, a metal cation or an amine or ammonio cation ##STR13## wherein each of R.sub.2, R.sub.3, R.sub.4, R.sub.5 independently represents hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkyl substituted by hydrogen or cyano, cyclohexyl, phenyl or benzyl, or two or three of the symbols R.sub.2 to R.sub.5, together with the nitrogen to which they are attached form a pyridine, piperidine, morpholine or picoline ring;
- and Z represents phenyl substituted by halogen, trifluoromethyl, cyano or nitro, or pyridyl substituted by halogen or trifluoromethyl, and the physiologically acceptable salts thereof.
