N-Phenylnaphthalen-1-amine (NPN) is an aromatic amine with the chemical formula C 16 H 12 NH. This molecule is notable for its binding affinity in mouse major urinary ...
The sulfonic acid derivatives of 1-naphthylamine are used for the preparation of azo dye.These compounds possess the important property of dyeing unmordanted cotton.. An important derivative is naphthionic acid (1-aminonaphthalene-4-sulfonic acid), which is produced by heating 1-naphthylamine and sulfuric acid to 170–180 °C in the presence of crystallized oxalic acid.
reduction of 1-nitroonaphthalene-8-sulfonic acid, precursor to C.I. Acid Blue 113 Notes: Peri-acid dehydrates to the sultam . Via the Bucherer reaction , heating periacid with anilinium salts gives the N-phenyl derivative, precursor to Acid Blue 113.
1,4-Naphthoquinone acts as strong dienophile in Diels-Alder reaction.Its adduct with 1,3-butadiene can be prepared by two methods: 1) long (45 days) exposure of naphthoquinone in neat liquid butadiene taken in huge excess at room temperature in a thick-wall glass tube or 2) fast catalyzed cycloaddition at low temperature in the presence of 1 equivalent of tin(IV) chloride: [5]
