Abstract

A novel method for performing structure correlations in solution is described. Examination of how the 13C chemical shifts of the ring carbons of substituted 2-pyridones change on complexation of the oxygen with silicon has enabled the% Si–O bond formation to be determined in solution for a number of pentacoordinate silicon species with 2-pyridones as ligands. The% pentacoordination in these complexes has been determined from the 29Si ...
