| abstract |
The invention discloses a method for synthesizing N-substituted sulfone diimine by photocatalysis, which comprises the steps of putting a sulfone diimine compound, bromide, inorganic base and a photocatalyst into a closed reaction tube, irradiating the reaction tube by a white light lamp at room temperature in an aprotic solvent under the atmosphere of inert gas for reaction, and carrying out aftertreatment to obtain the N-substituted sulfone diimine. Wherein the photocatalyst is iridium catalyst. The method of the invention adopts the photocatalyst, can carry out reaction under the condition of illumination at room temperature, has mild reaction condition and wide applicable substrate range. |
