H. Koroniak et al., F-19 NMR PROPERTIES OF SOME TRIFLUOROVINYL-SUBSTITUTED AND PENTAFLUOROPROPENYL-SUBSTITUTED AROMATICS, Magnetic resonance in chemistry, 31(8), 1993, pp. 748-751
F-19 NMR chemical shifts and coupling constants are given for a series
of aryl (phenyl, naphthyl and phenanthryl) substituted trifluorovinyl
s and (E)- and (Z)-perfluoropropenyls. The relationship between the F-
19 NMR chemical shifts and the configurational orientation of the perf
luoroalkenyl substituents is discussed.
