Abstract
With the advancements in materials engineering, unprecedented newer materials based on magnetic MOFs have emerged as one of the promising candidates in the strategic field of catalysis. Within this perspective, the present report unveils the fabrication of an intricately designed magnetic CoFe2O4/Ni-BTC based MOF composite via a one-pot solvothermal approach. The synthesized composite was comprehensively characterized using various analytical tools such as FTIR, XRD, XPS, VSM, TGA, EDS, ED-XRF and AAS. Advanced microscopic tools like SEM and TEM provided deep insights into the structural aspects of the synthesized material. The catalytic performance of the hybrid composite was further explored in one-pot multicomponent reactions to obtain a combinatorial library of biologically and pharmacologically significant 2,4,5-trisubstituted (up to 98% yield) and 1,2,4,5-tetrasubstituted (up to 97% yield) imidazoles in good to excellent yields under solvent free conditions. Wider functional group tolerance, excellent turnover numbers, high atom economy, ambient reaction conditions, magnetic retrievability and good recyclability are some of the striking attributes of this protocol. We envisage that the present methodology employing magnetic MOFs as catalytic reactors is highly desirable for designing cleaner and greener processes in modern organic chemistry.
