Selenium in Organic Synthesis: A Novel Route to 1-Phenylselenobutadienes and 1,4-Dicarbonyl Compounds

Two approaches to 1-phenylseleno-1,3-butadienes 5 are reported, via phenylselenoalkenylidene phosphoranes and phenylselenoalkenals, respectively. 1,4-Dicarbonyl compounds are prepared from the 1-phenylselenobutadienes or from the phenylselenoalkenals.

Treatment of alcohols with tert-butyl hydroperoxide in the presence of diaryl diselenide in refluxing benzene gives the corresponding aldehydes or ketones.Although some allylic alcohols undergo oxidation in the presence of 10-15 mol percent of bis(p-chlorophenyl) diselenide, use of 0.5 equiv of bis(2,4,6-trimethylphenyl) diselenide gives satisfactory results in almost all cases.The procedure can be used for selective oxidation of alcohols bearing a phenylthio or phenylseleno group, which usually survives the reaction conditions to give the corresponding carbonyl compounds.
