Rout, Kanhu Charan published the artcileAromatic C-nitrosation by a copper(II)-nitrosyl complex, Recommanded Product: 4-Amino-3-hydroxynaphthalene-1-sulfonic acid, the publication is Dalton Transactions (2015), 44(4), 1829-1835, database is CAplus and MEDLINE.
Copper(II) complex of 4-amino-3-hydroxynaphthalene-1-sulfonic acid was synthesized and characterized. Upon addition of nitric oxide, the copper(II) center of the complex in methanol undergoes reduction through an unstable copper(II)-nitrosyl intermediate. The formation of the intermediate was confirmed by UV-visible and FTIR spectroscopy. The reduction of the copper(II) center was accompanied with a simultaneous C-nitrosation of the aromatic ring of the ligand. The C-nitrosation product was isolated and characterized by various spectroscopic analyses.
