The invention discloses a method for electrochemically synthesizing sulfur ylide compounds by utilizing continuous flow. The method of the invention conducts the reaction in an electrochemical flow synthesis device on a microscale, and dissolves phenothiazine compounds, active methylene compounds, alkalis and electrolytes in a mixed solvent to obtain a reaction solution, and the reaction solution enters the reaction through a syringe pump In the module, the constant current reaction is connected, and after the reaction is completed, the filtrate is separated by column chromatography to obtain sulfur ylides. Compared with the prior art, the present invention creatively develops a new method for preparing sulfur ylide compounds by continuous flow electrochemical oxidation reaction without traditional transition metals and oxidants. |
