P-FLUOROBENZALDEHYDE AND P-FLUOROBENZOIC ACID BY OXIDATION OF P-FLUOROBENZYL DERIVATIVES

Experiments on the oxidation reactions of p-fluorobenzyl alcohol and c hloride were carried out. Several oxidizing agents (manganese dioxide, 30% hydrogen peroxide and hypochlorite solutions at different concent rations) were used, and a mixture of p-fluorobenzaldehyde and p-fluoro benzoic acid in different proportions was obtained. In the case of p-f luorobenzyl chloride, some p-fluorobenzyl alcohol was also found in th e reaction mixture. The experimental conditions required to obtain an increase in the yield of the aldehyde or acid were also studied. (C) 1 998 Elsevier Science S.A.
