General description

Kinetics and mechanism of gas-phase elimination of trimethyl orthoacetate has been examined over the temperature range of 310-369°C and pressure range of 50-130Torr.

Trimethyl orthoacetate is used to synthesize acrylonitrile intermediates via reaction with alcohols followed by Knoevenagel condensation.

Application

Trimethyl orthoacetate has been used in the preparation of 2-amino-9-(3-acyloxymethyl-4-alkoxycarbonyloxybut-1-yl)purines and 2-amino-9-(3-alkoxycarbonyl-oxymethyl-4-alkoxycarbonyloxybut -1-yl)purines.
