Nitriles used to be known as cyanides; the smallest organic nitrile is ethanenitrile, CH3CN, (old name: methyl cyanide or acetonitrile – and sometimes now called ethanonitrile). 31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Nitriles are found in many useful compounds, including methyl cyanoacrylate, used in super glue, and nitrile rubber, a nitrile-containing polymer used in latex-free laboratory and medical gloves.

Malyasova, A. S.;Kostrova, E. A.;Abramov, I. G.;Maizlish, V. E.;Koifman, O. I. research published 《 Synthesis, acid-base interactions, and photostability of copper(II) tetrakis(3,5-di-tert-butylbenzoyloxy)phthalocyanine》, the research content is summarized as follows. 3,4-Dicyanophenyl 3,5-di-tert-butylbenzoate was synthesized for the 1st time. Copper tetrakis(3,5-di-tert-butylbenzoyloxy)phthalocyaninate was also obtained for the 1st time using template cyclotetramerization. Compounds were identified by UV-visible, IR, 1H and 13C NMR spectroscopies. The features of the acid-base interaction and the acidity constants of the copper tetrakis(3,5-di-tert-butylbenzoyloxy)phthalocyaninate protonated forms, as well as Cu tetra(4-tert-butyl)phthalocyaninate and its ligand in the system CH2Cl2-100% HO2CCF3 were studied. The macrocycle’s protonation includes two reversible stepwise reactions, namely, mono- and diprotonation at the meso N atoms. The acidity constants dependence on the chem. structure of mols. was revealed. The phthalocyanines photocatalytic stability in benzene was also studied. An increase in the electron-donating properties of the macrocycle decreases the complex stability, and vise versa, a decrease of the electron d. in the macrocycle increases the photostability.

4-Nitrophthalonitrile is a chemical substance that can be synthesized by the reaction of sodium carbonate with 3,4,5-trimethoxybenzyl alcohol. It can also be prepared using nitro phenol and sodium hydroxide. 4-Nitrophthalonitrile has been shown to have high photochemical activity in the presence of light. The frequency shift of its infrared spectrum is indicative of a nucleophilic addition reaction mechanism. 4-Nitrophthalonitrile has been used as an intermediate for producing other chemicals, such as herbicides and pharmaceuticals., 31643-49-9.
