1,8-Bis(dimethylamino)naphthyl-2-ketimines: Inside vs outside protonation

1,8-Bis(dimethylamino)naphthyl-2-ketimines: Inside vs outside protonation

The structure and protonation behaviour of four ortho-arylketimines of 1,8-bis(dimethylamonio)naphthalene with a different number of methoxy groups in an aromatic substituent were investigated in solution by NMR (acetone, DMSO, MeCN), in solid state by X-ray analysis and in the gas phase by DFT calc...
