-((Phenylimino)methyl)naphthalen-1-ol and 4-((phenylimino)methyl)-2-(piperidin-1-ylmethyl)naphthalen-1-ol have been synthesized and their tautomeric properties were investigated using mol. spectroscopy (UV-vis absorption/emission and NMR), X-ray crystallog. anal. and quantum-chem. calcns. The results show that with the implementation of a flexible piperidine ring a controlled shift in the tautomeric equil. will be achieved upon protonation/deprotonation in acetonitrile. The addn. of a metal salt also shifts the tautomeric equil., but at very high concns., which is caused not by a complex fo...
