Abstract:2-Bromo-6-fluorobenzyl bromide,2-Bromo-6-fluorophenyl methanol, 2-Bromo-6-fluorobenzoic acid and 2-Bromo-6-fluorobenzaldehyde were prepared from 2-Bromo-6-fluorotoluene by bromination,hydrolysis,oxidation and Sommlet reactions.And the synthesis process had been studied in this paper.The result showed that HBr/H2O2 as brominate agent,the yield of 2-Bromo-6-fluorobenzyl bromide was 90.3%;ethanol as solvent,the yield of 2-Bromo-6-fluorophenyl methanol was 92.8%;In the oxidation reaction,2-Bromo-6-fluorobenz- oic acid gived 58.2% with KMnO4,and under the condition of n(2-Bromo-6-fluoro benzyl bromide):n(Methenamine)=1.0:1.3,the yield of 2-Bromo-6-fluorobenzaldehyde was 79%.All products structures were characterized by nuclear magnetic resonance and infrared.
