Abstract

Introduction of a chiral ligand to a series of pentacoordinate silicon complexes led to the assignment of two intramolecular rate processes: Si-N cleavage and pseudorotation. Linear correlations between ¹⁵N and ²⁹Si chemical shifts of the complexes, as well as between the latter and the N-methyl exchange barriers were attributed to variation in strength of N→Si coordination.
