µ-Nitrido Bridged Diiron Phthalocyanines: Old Complexes for New Catalytic Applications

Abstract

Binuclear N-bridged M-N-M (M=transition metal) complexes on phthalocyanine platform constitute an emerging class of oxidation catalysts. Their unusual structure provides unprecedented catalytic properties and reactivity. The most significant so far example is the mild oxidation of methane. In addition to oxidation of strong C-H bonds in alkanes, aromatic and alkylaromatic compounds μ-nitrido diiron phthalocyanines catalyze the formation of C-C bonds exemplified by hydroacylation of olefins with aldehydes. A clean and practical character of this system coupled with real availability of the phthalocyanines suggests a high application potential of this approach. This system has a great potential for further development by modification of the structure.
