实验过程

Tetrafluorosuccinic acid (500 mg, 2.63 mmol) was dissolved in 10 ml of distilled water. Guanidine carbonate (474 mg, 2.63 mmol) was added at room temperature (carbon dioxide gas was evolved) and the reaction was stirred at room temperature for 2 hours. The water was removed in vacuo with heating to approximately 90° C. for 4 hours. The product was isolated as a white solid.
