Redistribution of terpy ligands—approaches to new dynamic combinatorial libraries
Abstract
Mixing solutions of homoleptic cobalt(II) complexes [CoA2]2+ and [CoB2]2+ results in the establishment of a combinatorial library containing the heteroleptic complex [CoAB]2+. By using enantiomorphic ligands A and B the reactions may be followed by 1H NMR spectroscopy. Exchange reactions with 6-substituted ligands are slower than those with 5- and 4′-substituted species.
