Synthesis of Homochiral CoIII– and MnIV–[2.2]Paracyclophane Schiff Base Complexes with Predetermined Chirality at the Metal Centre

The planar chiral Schiff base ligand 2, derived from (R-p)-5-formyl-4-hydroxy-[2.2]paracyclophane (FHPC) (1), was utilised to form a Lambda-Co-III cis-beta-octahedral metal complex 3 with complete control of the metal-centred chirality. In addition, a di-mu-oxo Lambda,Lambda-Mn-IV complex 4 was synthesised with control of both metal-centred and (P)-helical chirality.
