Synthesis and characterization of benzothiazolyl-substituted anils.
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.
