Carbon-13 nuclear magnetic resonance study of phenyl derivatives of B, Si, Sn, P, and Te fluorides

13C nuclear magnetic resonance data for a variety of phenyl derivatives of boron, silicon, tin, phosphorus, and tellurium fluorides are presented. Neutral, anionic, and cationic complexes are included and the coordination number of the central element varies from 3 to 6. Empirical equations of the 13C chemical shifts of the benzene ring have been deduced by taking into consideration the charge density, dipole moment, and binding energy, and the 13C chemical shifts calculated from these equations deviate from the experimental values by up to 1.4 ppm, but mostly less than 0.7 ppm.
