Multi-functional Fe-Al0.66DTP/MCF catalyst in cascade engineered synthesis of the drug butamben: Novelty of catalyst, reaction kinetics and mechanism

Bimetallic Cu–Ni Nanometal Supported over Mesocellular Silica Foam As a Novel Catalyst for One-Pot Synthesis of Benzimidazole in DMF As a Bifunctional Reagent

“…Figure represents the XRD of (a) MCF, (b) Cu–Ni@MCF, (c) reused Cu–Ni@MCF, (d) Cu–Pd@MCF, (e) Ni@MCF, and (f) Cu@MCF, which are in accordance with that described in the literature. ,− The diffractogram for MCF showed a single broad peak, at a 2θ value of ∼22°. The XRD patterns for fresh and reused 10% (1:1) Cu–Ni@MCF catalyst could not be obtained properly due the amorphous nature of the catalyst, low amount of metal loading, and incorporation of nanometals into the support.…”

“…can be done skillfully due to a good porosity of the material. Mesocellular silica foam (MCF) is popular for its higher pore diameter and volume compared to many supports. − Thus, it can be chosen to obtain a high surface area catalyst support with higher stability and comparatively fewer requirements of the quantity of the nanometal catalyst to be incorporated on its entire pore surface, thus reducing the overall cost of the catalyst. , …”

Highly selective esterification of bioderived itaconic acid to monobutyl itaconate: kinetic analysis of a reusable 20% (w/w) Rb0.5Cs2.0H0.5PW12O40/MCF catalyst system

“…Our laboratory reported the use of multi-functional catalyst Pd-DTP@ZIF-8 for one-pot synthesis of 3-phenyl propyl benzoate by esterification reaction, 54 20% (w/w) Cs-DTP/K-10 for a single step synthesis of 4-hydroxy benzophenone via esterification and Fries rearrangement 55 and a multi-functional Fe-Al 0.66 DTP/MCF catalyst for hydrogenation followed by esterification as a cascade engineering approach for the synthesis of drug butamben. 56 These diverse catalysts represent significant advancements in the quest for efficient and sustainable catalytic processes. Although hetero-poly acids and their modified form as catalysts can provide the necessary, mild acidic conditions for the selective esterification of itaconic acid, there is no report of their uses.…”
