摘要：

The course of nucleophilic substitution at silicon involving a pentacoordinate intermediate is mapped in solution; 1 the method involves correlating the extent of nucleophile-silicon bond-making (as determined by the pyridone ring carbon chemical shifts) with the coordination state of the silicon (as inferred from the Si-29 NMR chemical shifts); the reaction under study is the displacement of X (X = OR, F, Cl, Br, OSO2CF3) by oxygen in an intramolecular reaction of a series of N-dimethylsilylmethyl pyridones.
