With strong electron-withdrawing functions in the naphthalene ring, it is possible to perform nucleophilic demethylation of free proton sponge bases. Thus, 1,8-bis(dimethylamino)-4-nitronaphthalene (7) at treatment with KOH in DMSO at 40 °C gave 1-methylamino-8-dimethylamino-4-nitronaphthalene (8) in 40% yield (a) A.F. Pozharskii, V.A.

Chem. 65 2000 7707 7709 there have been described some examples of oxidative monodemethylation, for which the formation of methyleneimmonium salt followed by its hydrolysis was assumed. The oxidative mechanism has been proved to be the main pathway for the biological demethylation of N,N-dimethylanilines

In order to estimate the reliability of calculated values for dipole moments of 8 and 9, Table 6 contains also the results of calculations according to the methods AM1 and PM3. They are compared with the similar data for parent proton sponge 3 and its 4,5-diformyl derivative 40, for which experimental values are also available. As it seen, for dialdehyde 40, there is a good agreement (deviation is less than 3%) between the experiment and the theory (both methods, AM1 and PM3, are almost equally acceptable). In the case of 3, the discrepancy for AM1 is inadmissibly big (∼30%), while for the PM3 method it is much less (∼10%). Therefore, the discussion of results is based on the PM3 data. It should be emphasized that, at the same time, the best correspondence in estimating the dipole moment of 3 gave ab initio calculations (see Ref. 26).
