Abstract
The synthesis of some "reverse pyridine" bis(phosphinite) pincer complexes of nickel and rhodium is reported. N-Functionalization of a POCOP ligand with a borane Lewis acid was found to permit cyclometalation with metal precursors, which reacted with the free base ligand in an undesired manner. Convenient removal of the coordinated Lewis acid was accomplished using polymer-supported 4-dimethylaminopyridine. The effects of borane Lewis acid coordination on the physical and spectroscopic properties of the pincer complexes were also assessed.
