This study presents the development of a novel nanocomposite catalyst, GO@SiO2@[(CH2)3Im][Cl], for the efficient one‐pot synthesis of 1,2,4,5‐tetrasubstituted imidazoles under environmentally benign conditions. The catalyst design incorporates graphene oxide, silica, and an imidazolium‐functionalized layer, creating a unique catalytic environment for ...

An efficient and solvent‐free sustainable one‐pot protocol is developed for the synthesis of broad range of dibenzoxanthenes using 5 mol% Bronsted acidic ionic liquid [VSBIM][Cl]. The versatility of the methodology was demonstrated by the effective synthesis of 19 dibenzoxanthene derivatives up to 90%–95% yields.

Pharmaceuticals Made with Hydrogen: A Sustainable and Efficient Approach Using Flow Synthesis
We demonstrate a sustainable strategy for pharmaceutical manufacturing by combining hydrogen, heterogeneous catalysis, and continuous flow synthesis. The development of novel catalysts and their application in a multi‐step synthesis of donepezil enabled a highly productive process with no intermediate purification.

ABSTRACT The rate of a heterogeneous catalytic process may simultaneously be described by several rate equations. In this case, discrimination between the plausible kinetic models is required. An intrinsic kinetic model of a heterogeneous catalytic process may successively be discriminated by the transition from a reaction rate‐limited regime to an ...
