Reaction Steps

To a 85 ml toluene solution containing 67.1 g (0.5 mole) of 2-allylphenol and 0.4 g of a 5% solution of H2PtCl6 in t-amyl alcohol is added a solution consisting of 15 ml of toluene and 38.8 g (0.25 mole) of 1,1,3,3-tetramethyldisiloxane at 75° C. The addition is complete in 1 hour. The mixture is heated at 85° C. for 1 hour and then at 105° C. for 3 hours. After washing successively three times with 100 ml portions of water, 101 g of the 2:1 molar adduct, 1,3-bis-(3-(2-hydroxylphenyl)-propyl)-1,1,3,3-tetramethyldisiloxane (>92% pure by gel chromatography, GC) having a light straw color is obtained after stripping off solvent. The structure of the product 1,3-bis-(3-(2-hydroxylphenyl)-propyl)-1,1,3,3-tetramethyldisiloxane is confirmed by 1H NMR and IR (neat).
