Abstract:
From 13C, 15N, 17O, 19F, 29Si, 31P, 73Ge, 77Se, 119Sn, and 125Te NMR data, it follows that complete replacement of phenyl hydrogen atoms by fluorine in compounds C6H5X leads to a systematic increase in shielding of nuclei in the ring carbon atom bonded to the X group and in shielding of the nucleus of the α-atom of X, along with deshielding of the nuclei of the Β- and γ-atoms of X. The effect evidently has a long-range character and can be described by the extended theory of Dewar and Kelemen.
