Yield:76241-02-6 80%
Reaction Conditions:
1,8-diazabicyclo[5.4.0]undec-7-ene in toluene at 120; for 3 h;
Steps:
3
A 1000 ml four-neck flask equipped with a refluxing cooler, stirrer, and thermometer was filled with 151.31 g (1.05 mole) of sodium benzoate, 100 g of toluene, 198.72 g (1.00 mole) of γ-chloropropyltrimethoxysilane, and 0.76 g (0.05 mole) of DBU, as a phase-transfer catalyst, and the mixture was stirred for 3 hours at 120°C. The obtained reaction product was separated by adding 240 g of water and purified by evaporating an organic layer via distillation in vacuum. It was confinned by a gas chromatography analysis that the final product was comprised of 227.59 g (0.80 mole) of trimethoxysilylpropyl benzoate. A yield of separation was relatively high and equal to 80%
