Descrizione generale

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.

Applicazioni

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.

New approaches to the synthesis of 4,7-dichloro-1,10-phenanthrolines and their corresponding 9H-carbazol-9-yl-, 10H-phenothiazin-10-yl- and pyrrolidin-1-yl derivatives were developed. Their properties have been characterized by a combination of several techniques: MS, HRMS, GC-MS, electronic absorption spectroscopy and multinuclear NMR in both solution
