Abstract Carbonyl compounds have been converted into 1, 3-oxathiolanes or 1, 3- oxathianes and then reduced with “mixed hydride” to β-hydroxyethyl (or on further reduction ethyl) or γ-hydroxypropyl sulfides, respectively. 1 However, this overall conversion of a carbonyl compound to a sulfide (a process for which the name reductive sulfidation is suggested) 2 is limited by the difficulties in transforming carbonyl compounds into acyclic ...
