1-Naphthylamine Usage And SynthesisChemical Propertiesα-Naphthylamine exists as white needle-like crystals which turn red on exposure to air. Has a weak ammonia-like odor. Solubility in water is 0.16% at 20℃. It behaves as a typical primary aromatic amine in forming salts with strong acids (but not with acetic or benzoic acid) and readily forming N-acyl derivatives. 1-Naphthylamine couples with diazo compounds in the 4-position, with up to 10 % byproduct being formed by coupling in the 2-position.Physical propertiesWhite to yellow crystals or rhombic needles with an unpleasant odor. Becomes purplish-red on exposure to air. Odor threshold concentrations were 140–290 μg/m3 (quoted, Keith and Walters, 1992).Uses1-Naphthylamine is used as a chemical intermediate in the synthesis of a wide variety of chemicals, the most important of which include dyes, tonic prints, Toning prints made with cerium salts, antioxidants, and herbicides.Preparation1-Naphthylamine is prepared by reduction of 1-nitronaphthalene: Purified 1-nitronaphthalene was traditionally reduced with iron in boiling dilute hydrochloric acid, but modern plants use hydrogenation with a nickel catalyst. The 1-naphthylamine produced is further purified by distillation under vacuum. The content of 2-naphthylamine in the commercial product is specified at <10 ppm.Application1-Naphthylamine is mainly used for the production of 1-naphthol. Other major uses are in the production of aminonaphthalenesulfonic acid dye intermediates and as a component of azo dyes.
1-Naphthylamine can also be used as a starting material to synthesize:
[(S)-HY-Phos], a novel chiral phosphine-phosphoramidite ligand for use in rhodium-catalyzed asymmetric hydrogenation of various functionalized olefins.
N-(naphthalen-1-yl)picolinamide.
Pitnot-2, an inactive analog of clathrin inhibitor Pitstop 2.
