NITRO DERIVATIVES OF NAPHTHALENE 433

STRUCTURE OF α− AND γ− ISOMERS

α− α− Trinitronaphthalene. Will [17] determined the constitution of this compound

from the following reactions:

α− Trinitronaphthalene can be formed by the nitration of 1,5-dinitronaphthalene.

When oxidized it yields o- nitrophthalic acid. Further nitration leads to 1,3,5-tetra-

nitronaphthalene :

.

(3a)

γ− γ− Trinitronaphthalene. The constitution of this isomer has been determined

from the reactions:
