Title
Nano titania-supported sulfonic acid: An efficient and reusable catalyst for a range of organic reactions under solvent free conditions
Abstract

•For the first time we have reported nano titania-supported sulfonic acid.•The n-TSA works very well for different organic reactions with good to excellent yields.•The advantages of n-TSA are high efficiently, reusability and operational simplicity.•The n-TSA was easily separated and reused for several runs without loss activity.

Nano titania-supported sulfonic acid (n-TSA) has been easily prepared from the reaction of nano titania (titanium oxide) with chlorosulfonic acid as sulfonating agent and characterized by the FT-IR spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermal gravimetric analysis (TGA). The catalytic activity of n-TSA was investigated in the synthesis of important organic derivatives such as pyrimidones, benzothiazoles and chalcones. All of the reactions are very fast and the yields are good to excellent. The catalyst was easily separated and reused for several runs without appreciable loss of its catalytic activity.
