3.3.3- trifluoropropan

Trifluoropropane (1342 g, 13.7 mol), HN03, and 02 (molar ratio 9.9-11.9 1 0.1-0.15) were treated at atmospheric pressure in the gas phase at 437-462 C for an exposure time of 1.7-2.0 s. Condensate collected at 0°C in the first trap and. after an aliquot was titrated for nitric acid (NaOH), was immediately extracted with Et20. The condensate collected at — 80 C in the second trap was distilled at atmospheric pressure to remove unreacted 1,1,1-trifluoropropane, then extracted with Et20. The ethereal extracts were combined, dried (Na2SQ4), and fractionally distilled on a packed column (80 x 1.5 cm, helices). After...

Elimination from 2-benzyl-1,1,1-trifluoropropane with potassium /-butoxide undoubtedly occurs through a carbanion-like E2 transition state. The structure of this substrate (14, Table 3, p. 192) is closely related to the pentahaloethanes known to react by the carbanion mechanism. The lesser tendency of the beta methyl and beta benzyl groups to withdraw electrons than the beta halogens accounts for a reduction in carbanion stability and a change to a concerted elimination.
