Gawinecki, Ryszard; Rasala, Danuta; Obrzut, Jan; Tamasik, Piotr published their research in Chemica Scripta on December 31 ,1985. The article was titled 《The ortho effect in pyridines. VI. Singlet → singlet π → π* excited state of 2- and 4-substituted 3-nitropyridines》.Application In Synthesis of 3-Nitroisonicotinic acid The article contains the following contents:
The UV absorption spectra in ethanol were measured for o-substituted nitrobenzenes, 2-substituted-3-nitropyridines and 4-substituted-3-nitropyridines. Based on bathochromic shift of the ICT band and its intensity, the ortho effect is discussed in the singlet→singlet π→π* excited state of investigated compounds In the experiment, the researchers used 3-Nitroisonicotinic acid(cas: 59290-82-3Application In Synthesis of 3-Nitroisonicotinic acid)
3-Nitroisonicotinic acid(cas: 59290-82-3) belongs to pyridine. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. As ligands, solvents, and catalysts they facilitate reactions; thus descriptions of these new ligands and their applications abound each year.Application In Synthesis of 3-Nitroisonicotinic acid
