Thiolesters can be conveniently prepared by the reaction of carboxylic acids with thiols and 1-fluoro-2,4,6-trinitrobenzene in the presence of 4-dimethylaminopyridine. The thiolester formation is found to be very effective for simple carboxylic acids.
A highly regioselective hydrocarbonylation of phenylacetylene with thiols and alcohols was developed using metal carbonyls/diazabicyclo[2.2.2]octane (DABCO) system at 100 °C in DMF. The use of Mo(CO)6 and thiols in the presence of DABCO was applied as an efficient Pd-free method for hydrothiocarbonylation of phenylacetylene into trans-α,β-cinamyl thioesters in excellent yields (88–98%).
