The Knoevenagel–Michael cyclocondensation of malononitrile, aryl aldehydes, and resorcinol was used as a multicomponent green tandem strategy for the metal-free synthesis of 2-amino-4H-chromene scaffolds. Through a visible-light-induced process, the photo-excited state functions derived from Na2 eosin Y were used as direct hydrogen atom transfer catalysts in aqueous ethanol at ambient temperature. The purpose of this study was to examine the further use of an organic dye that does not contain metal and is inexpensive and commercially available. Na2 eosin Y is synthesized by photochemical means using the least amount of catalyst, which results in excellent yields, energy efficiency, and environmental friendliness, high atom economy, time-saving features, and ease of operation. As a result, some properties of green and sustainable chemistry are met. This kind of cyclization can be performed on a gram scale, indicating the potential utility of this reaction in industry.

“…4,5 MOFs have attracted great attention for various applications in the fields of drug delivery, sensors, hydrogen gas storage, separation, catalysis and adsorption of hazardous waste. 6,7 In continuation of our research work on the development of active catalytic materials, 8,9 herein we report the synthesis, characterization and catalytic application of Zn-based MOF as an efficient heterogeneous catalyst. It was synthesized by a solvothermal method and characterized using powder X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDAX), Fourier transform infrared (FTIR) spectroscopy and Brunauer-Emmett-Teller (BET) surface area analysis.…”

BACKGROUND A mesoporous zinc‐based pyridine‐2,5‐dicarboxylate metal–organic framework (Zn‐based MOF) catalyst was prepared by a solvothermal method. The catalytic potency of Zn‐based MOF for the one‐pot synthesis of 3,3‐(arylmethylene)bis‐1H‐indole derivatives was investigated. RESULTS Various analytical techniques were used to characterize the physicochemical structure of Zn‐based MOF catalyst, including powder X‐ray diffraction, thermogravimetric analysis, scanning electron microscopy–energy‐dispersive X‐ray analysis, Fourier transform infrared spectroscopy and Brunauer–Emmett–Teller surface area analysis. Zn‐based MOF was then employed as a catalyst for the catalytic one‐pot transfer synthesis of 3,3‐(arylmethylene)bis‐1H‐indole derivatives. Optimizations of Zn‐based MOF catalyst in terms of effect of solvent and reaction time were investigated. CONCLUSIONS Zn‐based MOF catalyst was synthesized by solvothermal treatment, characterized and used as a Lewis acid catalyst for the synthesis of biologically active 3,3′‐(arymethylene)bis‐1H‐indole derivatives. The catalyst offers notable benefits such as reusability of catalytic character, easy separation, nontoxicity, large pore size and providing excellent yield of 3,3′‐phenylmethylene‐1H‐indole derivatives. Zn‐based MOF was confirmed as containing tetragonal phase with large pore diameter, morphology looking like a spherical core and exhibiting no significance loss of catalytic performance when used in organic synthesis for three to four reaction runs. Thereby Zn‐based MOF was evidenced as showing excellent catalytic activity. © 2022 Society of Chemical Industry (SCI).
