The synthesis of the iron phthalocyanine bearing four fused tetraazamacrocycles starting from N,N',N″,N‴-tetrakis(p-tolylsulfonyl)triethylenetetraamine and 1,2-dibromo-4,5-bis(bromomethyl)benzene is reported. The exchange of protecting tosyl groups by acetyl groups was necessary to obtain iron phthalocyanine. The efficiency of iron phthalocyanine as oxidation catalyst was tested for the practically important oxidation of 2,3,6-trimethylphenol (TMP) at different reaction conditions.

Abstract57Fe isotope-enriched iron phthalocyanine has been synthesized and studied by the Mössbauer spectroscopic method. The samples were investigated in the temperature range 100–350 K. Some peculiarities in atomic and molecular electronic structure fluctuations were observed. The intermediate Fe oxidation states are observed and it has been found that the rate of charge redistribution is temperature-dependent. The correlation between the temperature behavior of the isomeric shift and quadrupole splitting has been demonstrated. At elevated temperatures above 300 K, the Fe2+ oxidation number is quasistable. The alteration of Fe oxidation number is associated with fluctuations of electron charges, and the electron-accepting and electron-donating properties of surrounding ligands. The energy barriers separating Fe oxidation states have been determined. The possibility of modeling Mössbauer spectra of electron-transfer systems has been shown.

Phthalocyanine Complex

We describe the synthesis and photophysical properties of tetraarylnaphthidines. Our synthetic approach is based on an iron-catalyzed oxidative C–C coupling reaction as the key step using a hexadecafluorinated iron–phthalocyanine complex as a catalyst and air as the sole oxidant. The N,N,N’,N’-tetraarylnaphthidines proved to be highly fluorescent with quantum yields of up to 68%.
