Dinitronaphthalene

Dinitronaphthalene refers to organic compounds with the formula C₁₀H₆(NO₂)₂. ^[1]

They are colorless or pale yellow solids. A mixture of the 1,6, and 1,8 isomers are produced by nitration of naphthalene, illustrating the tendency of electrophiles to attack separate rings on the naphthalene. The 1,4-isomer is prepared by a less direct route from 1-nitro-4-aminonaphthalene via a diazonium intermediate. ^[2]
