alpha -Phenoxy-thiolpropionic acids

摘要

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