Ketones were obtained in good yields by titanocene(II)-promoted reaction of thioacetals with alkanenitriles. The regioselective formation of α-substituted ketone was observed when the reaction was carried out in the presence of methyl iodide or benzyl bromide.

Hydroboration of 1-alkylthio-1-alkynes with dicyclohexylborane or bis(1,2-dimethylpropyl)borane proceeded smoothly, adding most of the dialkylboryl group to the α-position of the triple bond. The resulting alkenylboranes afforded either S-alkyl alkanethioates on a controlled oxidation with alkaline hydrogen peroxide in the presence of N,N,N′,N′-etramethylethylenediamine or (Z)-1-alkylthio-1-alkenes on a basic protonolysis, successive treatments with methyllithium, copper(I) iodide and water in the presence of hexamethylphosphoric triamide.

Mild reaction of pheyl vinyl sulfides with dioxygen can lead to the eventual formation of rearranged vinyl sulfides and/or carbonyl-containing sulfide products, which are believed to result from decomposition of initially-formed vinyl sulfideradical cations. Supporting evidence is provided by the comparable findings obtained from the one electron oxidation of one vinyl sulfide by cerium (IV) ammonium
