Abstract

Structural studies of seven complexes of ligands derived from various azetidine- and oxetane-containing ligands characterise the difference in reactivity of both free and bound forms of these two four-membered heterocycles. The relatively unreactive azetidine ring is preserved in a variety of transformations, whereas facile opening of the oxetane ring provides a convenient pathway to complexes with pendent functionality.

Notes

  1. Where the coordination preferences of the metal ion are such that this binding is not favoured, the ligand, bound quadridentate in a square-planar species, appears to prefer the common, cyclam-like conformation where both six-membered chelate rings adopt the chair conformation [33]
