Sulfated titania (TiO2‐SO42−) is a unique and versatile catalytic material which is non‐toxic, non‐corrosive, non‐pollutant and easily separable in nature. Sulfated titania can engage in various organic reactions, as it contains both Lewis acid and Bronsted acid sites. A wide number of organic reactions in the presence of sulfated titania have been reported, most of which displays excellent conversion and selectivity for the syntheses of desired products with significant applications. This review endeavors to give an overview of the research highlights solicitous with sulfated titania. Even though it is arduous to cover all the research articles in the literature, various milestones in the route towards highly functionalized sulfated titania are explored. It is hoped that this review article will trigger the attention of researchers over sulfated titania for the advancement of new eco‐compatible approaches in organic chemistry.

A heterogeneous and hard bound TiIV anchored MCM‐41 material has been successfully evaluated for catalytic applications in the one pot synthesis of highly functionalized β‐amino ketones and quinoline appended π‐conjugated imines via Mannich reaction and condensation reaction, respectively. The synthetic transformation was successfully catalyzed via the dual Bronsted and Lewis acetic nature of the Ti‐MCM‐41 material that provided excellent yields of the desired products. The heterogeneous catalyst shows good catalytic performance, facile separation from the reaction mixture and can be reused in more than five catalytic cycles without any significant loss in the yield.
