A new electrochemical procedure was developed for preparing 2,4,6-triphenylselenopyran from 1,5-diketones under conditions of acid catalysis at oxidative electrochemical activation of hydrogen selenide in the presence of a one-electron oxidizing agent in a nonaqueous solution. The electrolysis products were analyzed by gas chromatography with a mass-selective detector.

The acid-catalyzed reaction of arylaliphatic 1,5-diketones with hydrogen selenide prepared in situ from zinc selenide in the presence of phosphorous acid derivatives yields 4H-selenopyrans. No disproportionation or addition of hydrogen selenide to multipl
REACTION OF 1,5-DIKETONES WITH HYDROGEN SELENIDE
