α-Aryl(alkyl)selenyl ketones have been important intermediates in organic transformation. Here, a new route to α-aryl (alkyl) selenoacetones via the electrochemical oxidated iodide promoted α-H aryl(alkyl)selenation of acetone by using stable and easy available diaryl(alkyl)diselenides as selenide reagent is reported. Comparing to the previous methods, this strategy has the advantages of mild reaction conditions, high atom economy and wide functional groups tolerance, providing an efficient and green route to α-aryl (alkyl) selenoacetones.

Key words: electro-organic synthesis, iodide-promoted reaction, α-H aryl(alkyl)selenation, α-aryl(alkyl)selenoacetones
