Inorganic compounds containing the −C≡N group are not called nitriles, but cyanides instead.31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Though both nitriles and cyanides can be derived from cyanide salts, most nitriles are not nearly as toxic. HPLC of Formula: 31643-49-9.
Moiseeva, Ekaterina O.;Kosov, Anton D.;Borisova, Nataliya E.;Tarasevich, Boris N.;Dubinina, Tatiana V.;Tomilova, Larisa G. research published 《 Tetraiodophthalocyanines: Simple and convenient synthetic protocol and structural modification via Sonogashira cross-coupling reaction》, the research content is summarized as follows. Planar and sandwich-type iodo-substituted phthalocyanines – precursors for cross-coupling reactions were synthesized starting from 4-iodophthalonitrile via a novel user-friendly synthetic strategy. For this purpose, 4-iodophthalonitrile was prepared following the multi-step protocol, including nonclassical version of diazotization/iodination reaction in the presence of p-toluenesulfonic acid. Tetraiodophthalocyaninato Zn(II) was obtained using a solvent-free microwave-assisted synthesis. For the 1st time, the polyphosphoric acid was applied to the demetalation of halogen-substituted phthalocyanine complex. Under these conditions, demetalation of Zn(II) complex occurred in a good yield without the oxidation of peripheral iodo groups. The Sonogashira cross-coupling reaction between the 2(3),9(10),16(17),23(24)-tetraiodophthalocyanine and model (trimethylsilyl)acetylene resulted in a target compound in a high yield (94%). The versatility of iodo-substituted phthalocyanine precursors was demonstrated on the examples of the synthesis of novel tetra-(3-hydroxyprop-1-yn-1-yl)- phthalocyaninato Zn (II) (52% yield), bis[tetra(2-trimethylethynyl)phthalocyaninato] Lu (III) (45% yield). Target compounds were identified by NMR, IR spectroscopy, and mass spectrometry. UV-visible properties of target compounds were studied and compared with literature data. The key compounds were characterized by elemental anal.
HPLC of Formula: 31643-49-9, 4-Nitrophthalonitrile, also known as 4-Nitrophthalonitrile, is a useful research compound. Its molecular formula is C8H3N3O2 and its molecular weight is 173.13 g/mol. The purity is usually > 95%.
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.
