Deprotection of 1,3-dithianes by antimony pentachloride via single electron transfer processes

Article abstract of DOI:10.1016/0040-4039(91)80123-N

A variety of 1,3-dithianes was converted to the corresponding carbonyl compounds in good yields when those substances were treated with antimony pentachloride in methylene chloride. Single electron transfer from dithianes to antimony pentachloride was proposed as an initiation step of the reaction.
