A very convenient and efficient modular approach for the synthesis of vicinal diamines containing axial chiral 1,1′-binaphthyl from 1,2-diaminoethane by Pd-catalyzed N-arylation reactions has been developed. The resulting chiral diamines could be easily c

On standard treatment of sterically congested alcohols and phenols with triflic anhydride 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 avoid unwanted sulfinate formation in triflate synthesis.
