چکیده انگلیسی
In (8-dimethylamino-naphth-1-yl) ('DAN') carbinols DAN-C(OH)R1R2, the N atom can approach the HO group unto Nâ¯H-O hydrogen bond distance only when the steric conditions are favourable. The energy gain of such Nâ¯H-O interactions is insufficient to force R1 and R2 into otherwise unfavourable conformations. The geometry of the naphthalene may cause N, O and C atoms to reside in positions similar to those typical for hydrogen bonds though no Nâ¯H-O and Nâ¯H-C hydrogen bonds may actually be involved. By analogy, it seems unlikely that in peri-donor/acceptor substituted naphthalenes D-C10H6-A dative interactions (DâA) of similar or less energy as such Nâ¯H-O interactions can interfere with the geometry conserving forces of naphthalene and the steric effects of the peri substituents.
