Porphyrin derivatives R 0130Synthesis of Imidazole and Imidazolium Porphyrins. -The title compound (IV) represents the first example of an imidazole covalently attached to the porphyrin periphery. -(SENG, V.; WANG, X.; ALI, R.; FANG, W.; CHARLES-PIERRE, F.; BHAGAN, S.; HYSLOP*, A. G.; J.

A new porphyrin compound, where an imidazole group was attached through the 1-position nitrogen to a phenyl ring located on the porphyrin periphery has been synthesized and characterized. The second nitrogen on the imidazole is available for further chemistry as demonstrated by the attachment of bromopentane forming the imidazolium porphyrin complex. This is the first example of an imidazolium group covalently attached to the porphyrin periphery in which the porphyrin is attached through the nitrogen on the imidazole ring rather than a carbon atom.
