determinations of salens were performed by the C"2+ t u 2 ' particularly effective in promoting selective functionalization of the substrate.' We now wish to report examples of the selective functionalization of substrates that can doubly bind to a metal-loporphyrin at appended metal ligand groups (Scheme I) and also to a related non-porphyrin metal epoxidation catalyst.
