Versuchsvorschrift

3,3-Difluorocyclobutanecarboxylic acid (Parkway Scientific, New York, N.Y., USA) (531 mg, 3.90 mmol) was dissolved in dichloromethane (3.00 mL) and oxalyl chloride (1.02 mL, 11.7 mmol) was added. The solution was stirred at room temperature for 4 h before concentrating in vacuo to provide 3,3-difluorocyclobutanecarbonyl chloride (ca. 50% pure), which was carried on without purification.
