EFFECTIVE SHIELDING VALUES OF THE PHENYL GROUP IN SOME GROUP IVB AND VB COMPOUNDS

Abstract

The effective shielding values of the phenyl group in silanes, germanes, stannanes, amines, phosphines and arsines are calculated from the proton magnetic resonance frequencies of protons attached to the group IVb or Vb element. The effective shielding of the phenyl group appears to be dependent on the electronegativity of the element to which it is bonded. The application of an additivity rule in calculating the frequency of protons in substituted silanes is shown.
