Electrosynthesis of o ,m ,p Trifluoromethylbenzoic Acids

The main reaction conditions such as cathode materials,temperature,etc.,in electrosynthesis of o ,m ,p trifluoromethylbenzoic acids from trifluoromethylphenyl halides in the presence of CO 2 were studied.The optimal conditions were obtained and the yields were up to 70%-80%.
