NOVEL LIGAND ORIENTATIONS IN PYRIDINE AND IMIDAZOLE COMPLEXES OF A HIGHLY SUBSTITUTED NONPLANAR PORPHYRIN, AND IMPLICATIONS FOR THE DESIGN OF PORPHYRINS AS REGIO-SPECIFIC AND STEREO-SPECIFIC OXIDATION CATALYSTS
Specific orientations are observed for pyridine and imidazole ligands complexed to a highly substituted nonplanar porphyrin, suggesting that suitably designed nonplanar porphyrins might be used to direct substrates and increase regio- and stereo-specificity in porphyrin catalysed oxidation reactions.
