Syntheses of New Aromatic Compounds with Fluorinated Side Chains and their Chemical Reactivity
The syntheses of a wide range of aromatic compounds of the type p-Y-C6H4CF2X(4-13) are described, and the chemical behavior of these compounds as a function of substituent Y is investigated .Analogously the pyridine derivatives 15, 17, and 18 were synthesized and characterized.From a correlation of the 19F-NMR data of these compounds with the Hammett constant of Y, participation of C-F ?-back-donation is seen as the cause for an observed shift of the 19F signals to lower field.
