Recent developments in the organic synthesis using nano-NiFe2O4 as reusable catalyst: A comprehensive synthetic & catalytic reusability protocol

Due to the alarming environmental hazards of the production of fine chemicals, medicines, and various kinds of compounds and minerals, the development of environmentally-friendly catalytic techniques has recently become of special interest. Accordingly, intensive research work was carried out in pursuit of abundant and sustainable catalysts that are eco-friendly. In particular, the employment of nano-nickel ferrite as a catalyst mitigates the waste impact of the and provides affordable synthetic approaches. This review paper addresses the recent advancements in synthetic organic processes that use nano-nickel ferrites as eco-friendly catalysts. In this review, we go over a number of frequently performed chemical reactions with nano-nickel ferrite acting as a catalyst. These include C-C and C -X (X = N, O, S) cross-coupling, cycloaddition, C-H annulation/functionalization, hydrogenation, aldehyde/ketone alkylation, oxidation, functional group removal and synthesis of heterocycles etc. The review paper also highlights the mechanistic course of reactions, recyclability protocols, synthetic processes, and their ap-plications in organic synthesis.
