Chiral ligand, chemical shifts

Summary 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 and Si 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. 

Lisowsky et a/. have studied proton pseudocontact chemical shifts in a series of chiral macrocyclic Yb(III) complexes which differ in the axial ligands. They...
