Highly reactive μ-carbido diiron tetraphenylporphine oxo-species: chemical generation and the oxidation ability

From mononuclear iron phthalocyanines in catalysis to μ-nitrido diiron complexes and beyond

“…In recent years, after extensive development of the catalytic chemistry of µ-nitrido diiron phthalocyanines and related complexes [60,61], the interest to the µ-carbido counterparts has been renewed. Despite their high oxidation states, µ-carbido diiron(IV,IV) porphyrinoid complexes were shown to be capable of reacting with peroxides to generate Fe(IV)Fe(IV) porphyrinoid cation-radical intermediates [100][101][102]. These high-valent species were proposed to be involved in the oxidation of 3,5,7,2',4'-pentahydroxyflavone [103], lycopene [104] and -carotene [105,106].…”
