General Description

2,3,6,7-tetramethylnaphthalene is a synthetic organic compound that is derived from naphthalene, a polycyclic aromatic hydrocarbon. It is a colorless crystal that is soluble in nonpolar solvents. This chemical is characterized by its four methyl groups that can be found attached to the naphthalene ring, and its formula is C18H18. It is used primarily as a component in the chemical synthesis of various pharmaceuticals and industrial compounds. Despite its usefulness in these areas, it should be noted that 2,3,6,7-Tetramethylnaphthalene, like other naphthalene derivatives, can pose a hazard due to its potential toxic and carcinogenic effects.

The question of aromaticity in open-shell cations and anions as ion-radical offsprings of polycyclic aromatic and antiaromatic hydrocarbons

(Chemical Equation Presented) Arene cation-radicals and anion-radicals result directly from the one-electron oxidation and reduction of many aromatic hydrocarbons, yet virtually nothing is known of their intrinsic (thermodynamic) stability and hence "aromatic character". Since such paramagnetic ion radicals lie intermediate between aromatic (Hueckel) hydrocarbons with 4n+2-electrons and antiaromatic analogues with 4n-electrons, we can now address the question of π-delocalization in these odd-electron counterparts. Application of the structure-based "harmonic oscillator model of aromaticity" or the HOMA method leads to the surprising conclusion that the aromaticity of these rather reactive, kinetically unstable arene cation and anion radicals (as measured by the HOMA index) is actually higher than that of their (diamagnetic) parent-contrary to conventional expectations.
