Conditions

Temperature: 90 °C

Procedure

Tetraethylorthosilicate (TEOS), 104 g, is loaded into a dried 1.3 L stainless steel pressure reaction vessel. A stoichiometric amount of trifluoroacetic anhydride, 105 g, is added. The reactor is sealed and the contents are heated at 80-100° C. for at least 12 hours. Preferably, the reaction is run at 80° C. for 16 hours. After sufficient time is permitted for conversion into the desired product, the reaction mixture is cooled and transferred to a vacuum distillation apparatus.
