Selective electrochemical fluorination of alkyl phenylacetates (Ph–CH2–COOR, where R is methyl, ethyl, n-propyl, n-butyl, i-propyl and sec-butyl) under galvanostatic conditions were reported in Et3N· 4HF medium. Preparative electrolysis experiments were carried out both in pre-electrolysed dry Et3N· 4HF and the same electrolyte medium without pre-electrolysis. Very little hydrolysed fluorinated products were obtained in pre-electrolysed medium ...
