Notizen:
An ‘anomalous’ variation of β-fluorine chemical shifts with respect to the inductive effect in the 19F NMR of a series of 1-halo-F-adamantanes is reported. These fluorine chemical shifts are similar to the hydrogen chemical shift anomaly found in the corresponding hydrocarbon halides. Whereas the γ-hydrogen chemical shifts can be rationalized by the inductive effect, the γ-fluorine chemical shifts have the same ‘anomalous’ variation as found in the β-fluorine chemical shifts.
