Reaktionsschritte
Malononitril (20.15 mmol) and 1-iodo-3,3,3-trifluoropropane (42.65 mmol) were dissolved in 30 ml dry THF, and the mixture was cooled with an ice/salt bath. 1.61 g NaH (40.3 mmol) was added portionwise, keeping the temperature below 5° C. The reaction mixture was stirred at room temperature for 2 hours and evaporated under reduced pressure. The crude material was purified by flash chromatography eluting with DCM, yielding 0.76 grams of an oil. 1H NMR (400 MHz, CDCl3) δ 2.62-2.49 (m, 4H), 2.31-2.24 (m, 4H)
