実験手順
3-Methyl-3-oxetane methanol (20.00 g, 0.1958 mole) and m-TMI (39.49 g, 0.1958 mole) were combined in a 250-ml four-neck round bottom flask equipped with a condenser, mechanical mixer, thermometer, nitrogen purge and oil bath. The reaction was placed under nitrogen with stirring and heated to 65° C. in the oil bath. A single drop of dibutyltin dilaurate was added and within 5 hours the reaction was complete based on depletion of the FT-IR isocyanate peak (2254 cm−1). The product was then removed from the flask as a colorless liquid with a viscosity of 21,000 cPs.
