Abstract
Novel penta-coordinated 2- and 4-substituted pyridine N-oxide silicon complexes were synthesized by the reaction of various 2- and 4-substituted pyridine N-oxides with silicon pinacolate. These complexes were characterized by 29Si NMR, 1H NMR and 13C NMR spectroscopy. The objectives of the present work is the study of influence of substitution at either 4 or 2-position of the pyridine N-oxide on the effect of the profile of pentacoordination.
