Steps:
IX Preparation of 3-(perfluorooctyl)ethyl isocyanate
A solution of crude [3- (PERFLUOROOCTYL)] propionyl azide (12 g) in toluene was put in a 500 mL round-bottom flask equipped with a condenser and a thermometer. The mixture was gradually warmed to [50-55 °C] over 1 h, and the temperature was maintained at around [55 °C] for 2 h. The mixture was then refluxed for 1 h. After cooling, the solvent was removed by a rotavap, the residue was distilled under high-vac to give non-color liquid that solidifies at room temperature.
