Two efficient acid-base-free procedures are introduced for the sulfenylation of cyclic enaminone compounds under aerobic and DMSO-oxidative conditions catalyzed by NaSO. According to procedures, a mixture of an aryl thiol and a cyclic enaminone are reacting together in DMF (aerobic oxidative conditions) or DMSO in the presence of a catalytic amount of NaSO (0.1 equiv in DMSO and 0.4 equiv in DMF) to
