Selenium showed excellent catalytic activity for carbonothiolation of alcohols with carbon monoxide and sulfur under mild conditions. S-Alkyl carbonothioates were synthesized in good yields from various alcohols, carbon monoxide, elemental sulfur, and alk

The first example of sulfur-assisted O-carbonylation is described.Alcohols react with carbon monoxide, elemental sulfur, and alkyl halides in the presence of DBU to give S-alkyl carbonothioates selectively in good to excellent yields.

Several sulfenyl thiocarbonates (RSSCO2CH3) have been decomposed with triphenylphosphine.In the case of R = alkyl, desulfurization takes place to give the S-alkyl thiocarbonate while in the case of R = aryl, a phosphonium salt is likely formed which on chromatographic workup on silica gel is converted to a thiol and triphenylphosphine oxide and sulfide.A mechanistic interpretation is offered.
