A series of aryloxy-substituted phthalodinitriles were prepared by nucleophilic aromatic substitution of bromine in 4-bromo-5-nitrophthalodinitrile, and the corresponding phthalocyanines were synthesized. The physicochemical properties of phthalocyanines depend on the substituent in the aryl moiety. 相似文献

The reactions of 4-phenyl-and 4-phenoxyphthalimide with benzoic acid in the presence of zinc(II) oxide gave zinc complexes of meso-tetraphenyltetra(4-phenylbenzo)porphyrin and meso-tetraphenyltetra(4-phenoxybenzo)porphyrin, respectively, and the latter were treated with hydrochloric acid to isolate the corresponding metal-free prophyrins. Spectral properties of the complexes and ligands were studied. 相似文献

Nucleophilic aromatic substitution of the bromine atom in 4-bromo-5-nitrophthalodinitrile by a 2-aminophenylamine residue followed by conversion of the resulting compound to 4-(1-benzothiazol-1-yl)-5-nitrophthalodinitrile and nucleophilic substitution of the nitro group by a 4-(1-methyl-1-phenylethyl)-phenoxy group gave 4-(benzotriazol-1-yl)-5-[4-(1-methyl-1-phenylethyl)phenoxy]phthalodinitrile. The latter product was reacted with certain metal acetates and chlorides to obtain the corresponding metal complexes of octasubstituted phthalocyanines. Spectral properties of the complexes were studied. 相似文献

Acid–base interaction of holmium(III) and lutecium(III) complexes with octaphenyltetraazaporphyrin in AcOH and AcOH–benzene and AcOH–H2SO4 systems was found to involve one nitrogen meso-atom. Stability constants of the obtained acid forms are determined. Solvoprotolytic dissociation of complexes in the systems based on AcOH is studied and its mechanism is discussed. 相似文献

The temperature dependences of the vapor pressure of calix[4]arenes were determined by the Knudsen effusion method. Some calix[4]arenes can form congruently subliming intramolecular compounds with a solvent. The thermodynamic parameters of the sublimation of the compounds were calculated. Molecules of organic solvents incorporated in the cavity of calix[4]arenes stabilize the crystal lattice, increasing the enthalpy of sublimation. The electrostatic interactions presumably make a significant contribution to stabilization of the crystal lattice of stoichiometric complexes of calix[4]arenes with solvents. 相似文献

Diazotization and nitration of 3,6-bis(4-amino-1,2,5-oxadiazol-3-yl)-1,4,2,5-dioxadiazine gave, respectively, 3,6-bis(4-azido-1,2,5-oxadiazol-3-yl)-1,4,2,5-dioxadiazine and 3,6-bis(4-nitroamino-1,2,5-oxadi-azol-3-yl)-1,4,2,5-dioxadiazine. The latter reacted with nitrogenous bases to form the corresponding salts. 相似文献
