, (2021)
FeCl3-catalyzed three-component aryl-selenylation of alkenes with good to excellent yields has been disclosed. This method is characterized by synthesis of complicated products in a single-step reaction, simple operation and readily available commercially reagents. Finally, a reasonable mechanism of FeCl3-catalyzed aryl-selenylation is proposed.

The invention discloses an aryl selenide compound and a synthesis method thereof, and the synthesis method comprises the following steps: dissolving styrene and/or styrene derivatives, electron-rich aromatic hydrocarbon and diselenide in an organic solvent, and uniformly mixing; and adding a catalyst, and reacting under the condition that the temperature is lower than the boiling temperature of the organic solvent to obtain the aryl selenide compound after the reaction is completed. The catalyst is utilized to catalyze the Friedel-Crafts alkyl selenylation reaction of styrene or styrene derivatives, the selenium-containing compound is synthesized through a one-pot method, the product can be obtained with good to very high yield, the substrate range is wide, and the yield is good in gram-level reaction.

(Chemical Equation Presented) Novel and efficient Bronsted acid (p-TsOH) catalyzed inter- and intramolecular Friedel-Crafts alkylations have been developed to synthesize selenated three-component coupling and selenation-cyclization indole derivatives. Chemical removal of the phenylseleno moiety was investigated, and the reaction mechanisms were discussed.
