ALPHA-PHENOXY-PROPANETHIOIC ACIDS AND SALTS, THEIR PREPARATION AND THEIR USE AS HERBICIDES OR INTERMEDIATES

摘要

The present invention concerns new alpha -phenoxy-thiolpropionic acids and salts of the formula 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.
