Helicity inversion from left- to right-handed square planar Pd(II) complexes: synthesis of a diastereomer pair from a single chiral ligand and their structure dynamism.

چکیده
A diastereomer pair of left- and right-handed square planar Pd(II) complexes was synthesized from a single chiral ligand as kinetic and thermodynamic products. Helicity inversion between the diastereomers occurred rapidly under thermal and microwave irradiation conditions.
