Reaction Conditions

Reaction Steps

A 1 liter 3 neck flask equipped with a magnetic stirrer, pot thermometer, dry-ice condenser and an addition funnel was charged with 106.6 g of allyloxymethyltetrahydrofuran. The flask was heated to 80° C., and 8.7 g of triethoxysilane was added, followed by 0.5 g of Karstedt's catalyst with a Pt concentration of 2%. An exotherm was observed and an additional 120.6 g of triethoxysilane was added while maintaining the temperature between 80°-100° C. After the addition was complete, an additional 0.25 g of Karstedt's catalyst was added, and the mixture was heated to 90° C. for 1 hour. The mixture was distilled through a short Vigreux column. Tetrahydrofurfuryloxypropyltriethoxysilane (98.7% purity by GC) was obtained in 60% yield, having a boiling point of 130° C./3 mm and a density at 25° C. of 0.9899.
