YieldReaction ConditionsOperation in experiment
96% polymer-bound Wilkinson's catalyst; In toluene; at 100 - 115??; for 48h;Heating / reflux; To a 100 mL round-bottom flask fitted with a magnetic stirrer and a reflux condenser were added 8.48 g (0.03 mol) of 1,1, 3,3, 5,5, 7,7-octamethytetrasiloxane, 8.70 g (0.075 mol) of 3-vinyl-7-oxabicyclo [4.1. 0] heptane, 40 mL of freshly distilled dry toluene. There were added 11 mg of polymer-bound Wilkinson's catalyst and the reaction mixture heated at 100-115C for 48 h by means of an oil bath. The course of the reaction was monitored using infrared spectroscopy by following the disappearance of the Si-H band at 2125 CM-1. When the infrared band had completely disappeared, the reaction was terminated and the reaction mixture filtered to remove the catalyst. The unreacted starting materials and solvent were removed under reduced pressure and high vacuum. After purification by flash chromatography over silica gel using chloroform as an eluent, there were obtained 15.3 g (96% theory) of the desired product as a colorless oil. 'H NMR (CDC13, 500 MHz) 6 (ppm) 3.12 (M, 4H, O-CH-EPOXY ring), 2.18-0. 77 (M, 18H, -CH2-CYCLOHEXANE ring), 0.48 (M, 4H,-CH2-Si), 0.04 (s, 24H, CH3-Si).
