The preparation and reactions of porphyrin N-oxides
Abstract
The reaction of octaethylporphyrin with hypofluorous acid and with permaleic acid gives a mono-oxygen adduct formulated as the porphyrin N-oxide, a novel chemical system. Octaethylporphyrin N-oxide is a sensitive molecule: it is gradually converted into octaethylporphyrin when manipulated under ordinary conditions. Examples of deoxygenation, nucleophilic attack at C-5, and metal complexation are described.
