Abstract: A novel and green method for the preparation of cobalt oxide nanosheets using pyridinium-based ionic liquid by simple reflux method is described in the present work. Pyridinium-based ionic liquid, N-butyl pyridinium bromide [BuPy]Br plays an important role as reaction media and morphology template to control Co3O4 nanostructures. This catalyst is characterized by XRD, FE-SEM, FT-IR, VSM and UV-Visible spectroscopy. Further, this nanocatalyst is used to catalyzes the condensation reaction of o-amino thiophenol with α,β-unsaturated ketones for preparation of 1,5-benzothiazepine derivatives in excellent yields. This efficient catalyst could be recovered and reused several times without any significant loss of activity.
