Abstract

Oxidation of a series of sulfides R′ SR (R′,dodecyl,phenethyl,benzyl,cumyl,benzhydryl; R,ethyl,phenyl) under photoinduced electron transfer conditions (sensitizers: 9,10-dicyanoanthracene,triphenylpyrylium tetrafluoroborate) yields sulfoxides,products of trapping of the alkyl cation (for the benzhydryl and cumyl derivatives),and mainly aldehydes or ketones that result from α -deprotonation. The competing paths from the sulfide radical cation are discussed in this paper.
