complexes has been determined from the 29Si chemical shift usingmodelcompounds for the tetracoordinate and pentacoordinate limiting cases. Correlation of the % Si–O bond formation with % pentacoordination enables the pathway for substitution at silicon to be mapped in solution. The generality of these techniques is examined using a series of related aromatic ligands.
