Versuchsvorschrift

Phenol (1.17 g, 0.0125 mole), trimethylsilyl trichloroacetate (3.53 g, 0.015 mole), potassium carbonate (0.035 g) and 18-crown-6 polyether (0.066 g) were placed in a 25-ml round-bottom flask fitted with a distillation head. A dry ice receiver and dry ice trap were attached. The mixture was heated to 150° C. Gas evolution proceeded rapidly and liquid chloroform and CCl3SiMe3 (formed by the base-induced decomposition of trimethylsilyl trichloroacetate) collected in the dry ice trap.
