and phenols with triflicanhydride in the presence of amines, trifluoromethanesulfinyl esters were unexpectedly found. Depending on the reaction conditions and the structures of both hydroxy compound and base, esterified products (yields <5% to 99%) containing 0% to 89% (!) of sulfinates were obtained. The mechanisms of these reactions are discussed. The results of the present study indicate how to
