Шаблон:Chembox 1,5-Diaminonaphthalene is an organic compound with the formula CШаблон:SubHШаблон:Sub(NHШаблон:Sub)Шаблон:Sub. It is one of several diaminonaphthalenes. It is a colorless solid that darkens in air due to oxidation.

Synthesis and reactions

It is prepared by reduction of 1,5-dinitronaphthalene, which in turn is obtained with the 1,8-isomers by nitration of 1-nitronaphthalene. It can also be prepared by treatment of 1,5-dihydroxynaphthalene with ammonium sulfite. It is a precursor to naphthalene-1,5-diisocyanate, a precursor to specialty polyurethanes.[1]
