General procedure: To a solution of (3,3-difluorocyclobutyl)methanol (4.0 g, 32.8 mmol) in dichloromethane (109 ml) at room temperature was added Dess-Martin Periodinane (16.7 g, 39.3 mmol). After 2 h, the reaction was diluted with two volumes of ether and treated with sodiumthiosulfate (32 g) in water (160 mL). After stirring at room temperature for 10 min, the layers were separated. The ethereal was washed with saturated sodium bicarbonate (2X), dried over magnesium sulfate, and filtered. The resulting solution was concentrated via distillation of the solvent through a short path distillation apparatus. The distillation was discontinued when 6.56 g remained in the boiling flask. Integration of the 1H NMR showed product as a 28.4 wt% solution in diethyl ether (1.86 g, 47% yield). The material was directly used without further concentration, 14774-37-9
