Cr. Wang et al., C-13 NUCLEAR-MAGNETIC-RESONANCE STUDY OF PHENYL DERIVATIVES OF B, SI,SN, P, AND TE FLUORIDES, Canadian journal of chemistry, 71(4), 1993, pp. 525-528
C-13 nuclear magnetic resonance data for a variety of phenyl derivativ
es of boron, silicon, tin, phosphorus, and tellurium fluorides are pre
sented. Neutral, anionic, and cationic complexes are included and the
coordination number of the central element varies from 3 to 6. Empiric
al equations of the C-13 chemical shifts of the benzene ring have been
deduced by taking into consideration the charge density, dipole momen
t, and binding energy, and the C-13 chemical shifts calculated from th
ese equations deviate from the experimental values by up to 1.4 ppm, b
ut mostly less than 0.7 ppm.
