Reaction Steps
A mixture of 11.6 g (0.058 mole) of freshly distilled 1-chloroethyl phenyl carbonate, 4.60 g (0.079 mole) of anhydrous KF (Aldrich), 0.80 g (0.003 mole) of 18-crown-6 ether (Aldrich) is prepared. The mixture is stirred and heated by means of an oil bath at 75° C. at a pressure of about 2.7 kPa. The reaction is allowed to proceed for 90 minutes during which the phenyl fluoroformate which is formed continuously evaporates and is removed by fractional distillation.
