  摘要：

  Previously unknown bis[1,8-bis(dimethylamino)naphth-2-yl]phenylmethanol (5) and bis[1,8-bis(dimethylamino)naphth-2-yl]methanol (6) have been obtained and studied by combination of X-ray, NMR, and IR techniques at variable temperature. It has been established that both proton sponge units in the solid tertiary alcohol 5 exist in nonconventional in/out form, one of which is fixed by intramolecular O-H center dot center dot center dot N hydrogen bonding. In solution, a fast interconversion of two isoenergetic hydrogen chelates occurs which can be frozen below 183 K. Unlike this, the secondary alcohol 6 in the solid at 100 K adopts the in/out-in/in conformation and at 293 K demonstrates a kind of dynamic behavior which can be described as temperature-driven dimer-induced rechelation. In solution under ambient conditions 6 exists as an equilibrating mixture of chelated and unchelated monomeric forms in a similar to 1:1.8 molar ratio.

  It has been shown that the 1-NMe2 group in the 2-substituted 1,8-bis(dimethylamino)naphthalenes (proton sponges) can intramolecularly donate a hydride ion to an appropriate electron-accepting ortho-substituent such as diarylcarbenium ion, β,β′-dicyanovinyl or methyleneiminium group. This produces the 1-N+(Me)CH2 functionality and triggers a number of further transformations (tert-amino effect) including
