摘要 |
<p>A process for producing aryloxy acetic acids and salts thereof which comprises reacting an alcohol of the formula R-OH wherein R is aryl or substituted aryl with a base in an aprotic organic solvent to give an aryloxide followed by removal of the organic solvent and reaction of the aryloxide with a salt of a monohaloacetic acid in a polar aprotic solvent such as DMSO to give the corresponding aryloxyacetate salt which then may be recovered or may optionally be converted to the corresponding acid by contacting the aryloxyacetate salt with an acid.</p> |
