Abstract

Schiff bases (imines) have been frequently used in various fields such as medicine, pharmaceutical purposes due to their various biological properties. In this study, nine new imine compounds (3a-h) were synthesized from 1-naphthyl amine with aromatic aldehydes in MeOH and their chemical structures were defined by 1H/13C NMR, IR and elemental analysis studies. We observed a singlet one hydrogen of the imines (–CH=N–) at 8.56–8.86 ppm in the 1H NMR spectra and also carbon of the Schiff bases (–CH=N–) at 158.2-163.4 ppm in the 13C NMR spectra. Also the IR spectra displayed the (–C=N–) characteristic absorption band at around 1600 cm -1. The obtained characteristic peaks at the expected locations proved the structural accuracy of the synthesized new derivative Schiff bases.
