| titleOfInvention | Method for preparing compound with spiro[5.5] molecular skeleton by electrooxidation |
| abstract | A method for preparing a compound with a spiro[5.5] molecular skeleton by electrooxidation is provided, which relates to the field of organic synthesis technology. Specifically, the method includes o-alkynyl benzoyl biphenyl reacts with sodium fluoromethylsulfite in an electrolyte and a solvent under a current condition to obtain the compound with the spiro[5.5] molecular skeleton. The method uses cheap CF3 (trifluoromethyl) free radical and electrooxidation to realize the de-aromatization of biphenyl without catalyst. The reaction can occur only under the action of current, which is energy-saving and economical. The free radical used in the reaction is cheap, easy to obtain and low cost. The reaction device is simple and easy to operate, and the yield of the reaction is as high as 60%. |
