“…Sorokin and colleagues used phthalocyanines as catalysts in oxidations with peroxides [179,180]. Thus, mild oxidation of ethane to acetic acid by H 2 O 2 was catalyzed by supported mu-nitrido diiron phthalocyanes [181], methane was oxidized to methanol, formaldehyde, and formic acid [182].…”

This review describes new reactions catalyzed by recently discovered types of metal complexes and catalytic systems (catalyst + co-catalyst). Works of recent years (mainly 2010-2016) devoted to the oxygenations of saturated, aromatic hydrocarbons and other carbon-hydrogen compounds are surveyed. Both soluble metal complexes and solid metal compounds catalyze such transformations. Molecular oxygen, hydrogen peroxide, alkyl peroxides, and peroxy acids were used in these reactions as oxidants.

“…It is likely that during these stages, mono-(reaction (13)) and dihydroxo-species (reaction (14)) are formed. The pK a of the first transformation (8.3±0.3) was found with a considerable degree of uncertainty because of an interference of a subsequent process.…”

A comparative study of reactivity of μ-nitridoand μ-oxo-dimers of iron tetrasulfophthalocyanine has been performed in aqueous solutions of various acidity. The substantially higher stability of the nitrido-bridged structure under both strongly acidic and strongly alkaline environments was demonstrated. The reactions of the complexes with sulfur-containing reductants (sodium dithionite, thiourea dioxide, sodium hydroxymethanesulfinate, L-cysteine) were studied. Differences in reduction processes were explained.

“…[30,31] In this context, assembling the iron porphyrin and phthalocyanine complexes in binuclear units provides catalysts with remarkable catalytic activity. [32][33][34][35][36][37][38][39] Although several crystal structures of iron(II) tetramesitylporphyrin complexes involving different pyridine and imidazole ligands, [40] 2-methylimidazole [41] as well as iron(III) tetramesitylporphyrin complexes with triphenyl-or triisopropylsilanethiolate, [42] 5-methylimidazole [43] and cyanide [44] ligands have been described, no supramolecular assemblies formed by iron tetramesitylporphyrin complex is available. Herein, we report X-ray structural studies of unusual supramolecular assembly consisting of four molecules of iron(III) tetramesitylporphyrin hydrosulfate complex [Fe(TMP)(OSO 3 H)] and two molecules of sulfuric acid formed due to intermolecular hydrogen bonding interactions during recrystallization of Fe(TMP)Cl from toluene/ H 2 SO 4 mixture.…”

We present here the first crystalline assembly of a supramolecular structure formed by iron(III) 5,10,15,20-tetrakismesitylporphyrin via hydrogen bonding with charge compensating hydrosulfate residues. Two additional molecules of sulfuric acid provide hydrogen bonding connection of four iron porphyrin units to form a fragment with interporphyrin void where two iron sites are situated at 9.52 Å distance. The insertion of two molecules of sulfuric acid into cavity formed by four Fe(III) porphyrin molecules led to the formation of the cluster structure with dihedral angle of 53.3° between adjacent porphyrin molecules Fe(1A)N 4 /Fe(2A)N 4 and parallel Fe(1A)N 4 /Fe(1B)N 4 and Fe(2A)N 4 /Fe(2B)N 4 planes. Such a supramolecular material, where four iron sites in the porphyrin ligand environment are strongly connected via network of the hydrogen bonds provides a new tool for exploring different applications involving multielectronic processes.
