Example 3. Preparation of an anion receptor (3); [Reaction Scheme 5]ClCHCCl3l-Iodo-3,5-bis-trifluoromethyl-benzene (3,5-Bis-trifluoromethyl-phenyl)-difluoro-amine 34g of l-iodo-3,5-bis-(trifluoromethyl)benzene (lOOmmol) and 35mL of tetrachloroethane were placed in a 10OmL round flask connected to a glass manifold system having an expansion valve, and the entire system went through 3 freezing – defreezing cycles under vacuum to remove air therein. The system was then filled with 6.7Og of tetrafluorohydrazine (64mmol), and the mixture was heated at 6O0C for 2 hours. During the heating process, the pressure was dropped from the lowest 525mmHg to 368mmHg. When excess gas fraction was analyzed by mass spectroscopy, it was discovered that 5.63g of tetrafluorohydrazine (54mmol) was consumed. Obtained dark colored solution was treated with mercury to remove iodine therein. A substantially transparent solution thusly obtained was then distilled to yield (3,5-bis-trifluoromethyl- phenyl)-difluoro-amine (see the Reaction Scheme 5).1H NMR (300MHz, CDCl3): ppm 7.75 (s, 2H), 8.05 (s, IH); 13C NMR (CDCl3): ppm 112.1, 113.2, 115.2, 119.6; 19F NMR (CDCl3): ppm -53.7, -64.12
