Synthesis and properties of phthalonitriles with an azo chromophore and related phthalocyanines

The 4-R-phenylazophenoxyphthalonitriles were synthesized by the reaction of 4-bromophthalonitrile with 4-R-phenylazophenols and were used to obtain tetra-R-phenylazophenoxyphthalocyanines and their metal complexes. The effect of substituents on the spectral and other properties of the synthesized compounds was established.

Synthesis and study of properties of the sulfonaphthylazophenoxyphthalonitrile and related phthalocyanine

The 4-[4′-(5-sulfonaphthylazo)phenoxy]phthalonitrile potassium salt was synthesized by the reaction of 4-chlorophthalonitrile with 5-(4′-hydroxyphenylazo)-1-naphthalenesulfonic acid, and on its basis was obtained tetra-4-[4′-(5-sulfonaphthylazo)phenoxy]phthalocyanine. The products were characterized by elemental analysis, IR and electron spectroscopy. The effect of the introduced substituent on the spectral and other properties of the synthesized compounds was demonstrated.

Bifunctional octasubstituted phthalocyanines. Synthesis and properties

Data on the synthesis of bifunctional octasubstituted phthalocyanines are reported. Some specificities of their electronic absorption spectra, thermal stability, and other properties, depending on the substituent nature and central metal ion, are revealed.

Unsymmetrical azaporphyrins. Synthesis, structure, and properties

Given are data on the synthesis and spectral and other physicochemical properties of unsymmetrically substituted azaporphyrins containing peripheral fused benzene and sulfur- or nitrogen-containing rings or phenyl substituents.

Synthesis and properties of lanthanide complexes with tetrapyrazinoporphyrazine and its substituted derivatives

Reactions of dicyanopyrazine and its tert-butyl-, diphenyl-, and dipyridyl-substituted derivatives with erbium, thulium, ytterbium, and lutetium chlorides, acetates, and acetylacetonates gave the corresponding tetrapyrazinoporphyrazine metal complexes which were characterized by elemental analyses, and IR, 1H NMR, and electronic absorption spectra. The stability of the complexes to thermooxidative decomposition in air was also studied.

Acid base interactions of octaphenyltetrapyrazinoporphyrazine and its complex with lutetium(III) in proton-donor media

Acid base interactions of octaphenyltetrapyrazinoporphyrazine and its complex with lutetium(III) in acetic and trifluoroacetic acid media were studied, and parameters characterizing equilibria between the acid and base forms were determined. Acid-base interactions of octaphenyltetrapyrazinoporphyrazine involve primarily nitrogen atoms in the pyrazine fragments, while its lutetium(III) complex undergoes protonation at the meso-nitrogen atoms.

Synthesis and Properties of Unsymmetrical Phenyl-substituted Porphyrazines

Abstract3-Amino-1,1-dichloro-5/6-phenyl-1H-isoindole hydrochloride was reacted with 5-amino-2-imino-3,4-diphenyl-2H-pyrrole or 5-amino-2-imino-3,4-ethylenedithio-2H-pyrrole to obtain unsymmetrical phenyl-substituted porphyrazines.

Synthesis and Spectral Properties of the Metallophthalocyanines with the Fragments of Substituted Pyrazoles

By the reaction of 4-bromphthalonitrile with corresponding 1-phenyl-3-methyl-5-hydroxy- and 1-p-sulfophenyl-3-methyl-5-oxypyrazolaes the substituted phthalonitriles were synthesized and converted into metallophthalocyanines with the fragments of substituted pyrazoles. The compounds obtained were identified using the data of elemental analysis, gas chromatography-mass spectrometry, IR, 1H NMR, and electronic spectroscopy. The influence of the peripheral environment of the phthalocyanine ligand in the resulting metal complexes on the spectral and other properties of the latter was revealed.

Erbium and ytterbium complexes with the phtalocyanines with aryloxy and chlorine substituents

By nucleophilic substitution of chlorine atoms in tetrachlorophthalonitrile by phenoxy- or 1-naphthyloxy groups aryloxychlorophthalonitriles were synthesized and on this basis respective substituted erbium and ytterbium phthalocyanines with chloro-, acetate- or acetylacetonate anions as extra ligands. The compounds obtained were characterized by elemental analysis, chromato-mass spectrometry, IR, 13C NMR, and electronic spectroscopy.

Synthesis and properties of metal phthalocyanines based on disulfophthalic acid

Octasulfo-substituted cobalt phthalocyaninate was synthesized from 3,5-disulfophthalic acid, and its ammonium salt was converted into the corresponding sulfonyl chloride by the action of chlorosulfonic acid. Treatment of the chlorosulfonyl-substituted phthalocyanine complex with aliphatic amines gave octaalkyl-sulfamoyl derivatives. The products were characterized by IR and electronic absorption spectra.
