Versuchsvorschrift

5 g (17.5 mmol) of tert-butyl 1,2,2,2-tetrachloroethyl carbonate dissolved in 10 ml of THF are added at 0° C. to a solution of imidazole (1.2 g; 17.6 mmol) in THF (20 ml) in the presence of 5M aqueous potassium carbonate solution (5 ml). The mixture is stirred for 1 hour at 20° C., and the organic phase is decanted and washed with 10 ml of saturated aqueous NaCl solution.

Aufarbeitung

  1. customthe organic phase is decanted
  2. washwashed with 10 ml of saturated aqueous NaCl solution
