実験手順

172 g (1.15 mol) of 4-tert.-butylphenol, 57.5 g (0.25 mol) of 2,2-bis-(4- hydroxyphenyl)-propane and 5 g of boron trifluoride etherate are stirred in an autoclave for 6 hours at around 150° C. The reaction mixture is then diluted with 400 ml of toluene and the catalyst washed out with 900 ml of water used in several portions. The solvent is then distilled off. 17.6 g (0.093 mol) of 5-hydroxy-1,1,3,3-tetramethyl indane were isolated from the 216.7 g reaction product by fractional distillation.
