    • Synthesis of 3: a solution of 2 (1.0 g, 1.72 mmol) in CHCl3 (5 mL) was added to a 1000 mL Erlenmeyer flask, and the solvent was allowed to evaporate slowly. A film of 2 was formed on the glass wall. Slow oxidation of a colorless film of 2 in the air after 2 months yielded a pink film containing 8% of 3 and 90% unreacted 2. When the film of 2 was first pretreated with dilute aqueous NaOH and then dilute aqueous HCl, the yield of 3 was 20% after exposure to air for 1 month. The film was dissolved in toluene (50 mL, After separation by preparative GPC (toluene elution, pink crystals of 3 were obtained in 15% yield. Anal. Calcd for C41H30-SiO2: C, 84.54; H, 5.15.
