Experimentelles 4: TACN (88.4 mg. 0.73 mmol), K,CO, (423 mg, 3.1 mmol) und R,CH,CH,CH,I (1.41 g. 2.41 mmol) wurden in DMSO (10 mL. von CaH, destilliert) gelost und 24 h auf 90 "C erhitzt. Perfluorheptan (20 mL) wurde zur Reaktionsmischung gegeben, die braune untere Phase wurde abgetrennt und dann filtriert. Nach Entfernen des Losungsmittels blieb ein hraunes 0 1 zuriick. Umkristallisieren aus heiBem Hexan lieferte 4 als gelbliches Pulver in 60% Ausbeute. FAB-MS: mjr: 1510 [ M + Hi]; Elementaranalyse (X): her. fur CH2.02,F64.31, N2.70; 1H-NMR(400MHz,CDCI,,25"C):6 = 2.71
