reactions of sulfoxides bearing α-hydrogen(s) (RSOCHR1R2: R-alkyl or aryl; R1, R2 = H, alkyl, or aryl) with Grignardreagents (R3MgBr: R3 = Et, Ph, or vinyl) in the presence of the diisopropylaminomagnesium reagent, generated in situ by the treatment of diisopropylamine with the appropriate Grignardreagents in diethyl ether, have resulted in the formation of the corresponding sulfides (RSCR1R2R3) in moderate

hydrothiolation of alkenes with thiols was achieved in the presence of 4-toluenesulfonic acid. Through this procedure, Markovnikov-type sulfides were synthesized in excellent yields, and the formation of anti-Markovnikov-type sulfides was suppressed. Furthermore, the combination of numerous aryl alkenes with arenethiols or alkyl thiols was achieved using the procedure.
