Abstract

New Schiff bases containing a hydroxynaphthyl ring and substituted benzothiazolyl groups have been synthesized. High‐resolution NMR spectra confirmed that these anils exist as enol–keto tautomers in solution. The results from NMR data demonstrated that the proportion of enol tautomer exceeded 90% in these substituted anils. Some compounds exhibited thermochromism in solid state.
