Allyl acetate → 3-(Trichlorosilyl)propyl acetate

Participants

Reaction Steps

In a 4-liter flask with stirrer, reflux condenser, internal thermometer and 2 dropper funnels, one filled with 800 g of allyl acetate and the other with 1.355 kg of trichlorosilane, 200 ml of allyl acetate was heated to 65°C. Then the heat source was removed, 1 ml of an 0.01 molar solution of mesityl oxide-platinum dichloride complex in allyl acetate was added, and the reaction was allowed to complete itself within 8 minutes while stirring was performed and the two reactants were fed in simultaneously. During that period the temperature rose to 105°C due to self-heating. After that no more silane hydrogen was detected analytically. Distillation of the reaction product yielded 2.28 kg of 3-acetyloxypropyltrichlorosilane, BP20 : 98°-100°C; nD20 : 1.4359.
