Process for the minimization of racemization in the preparation of optically active ((aryloxy)phenoxy)propionate herbicides

One of the routes to prepare optically active 2-(4-aryloxyphenoxy)propionic acid ester herbicide is to couple optically active 2-(4-hydrophenoxy)propionic acid esters with halogenated aromatic or heteroaromatic compounds. Conversion of the optically active 2-(4-hydroxyphenoxy)propionic acid ester into the acid salt prior to the coupling step effectively prevents the racemization that unexpectedly occurs otherwise.
