A new role for photoexcited Na2 eosin Y as direct hydrogen atom transfer (HAT) photocatalyst in photochemical synthesis of dihydropyrano[2,3-c]pyrazole scaffolds promoted by visible light irradiation under air atmosphere

Evidence indicates that Na2 eosin Y-derived photoexcited states functions as a direct hydrogen atom transfer (HAT) catalyst to synthesize dihydropyrano[2,3-c]pyrazole scaffolds photochemically via four-condensation domino reaction of tandem Knoevenagel-Michael cyclocondensation reaction ethyl acetoacetate, hydrazine hydrate, aryl aldehyde derivatives and malononitrile via visible light-mediated in aqueous ethanol at ambient temperature under air atmosphere. This study paves the new role for further the use of a metal-free organic dye with commercial availability and inexpensiveness, Na2 eosin Y in photochemical synthesis with use of the lowest amount of catalyst, excellent yields, time-saving aspects of the reaction and high atom economy. Notably, this cyclization is also runnable on the gram scale, which highlights the potentiality of using this reaction in industrial uses.

Magnetization of biochar nanoparticles as a novel support for fabrication of organo nickel as a selective, reusable and magnetic nanocatalyst in organic reactions

Catalyst species are an important class of materials in chemistry, industry, medicine and biotechnology. Also, waste recycling is an important process in green chemistry and economic efficiency. Therefore, in order to recycle waste, biochar nanoparticles were prepared from chicken manure. Then, the biochar nanoparticles were magnetized under a green and environmentally friendly method. Finally, the surface of the magnetic biochar nanoparticles was modified and further they were applied as a novel support for fabrication of nickel as a homoselective and reusable catalyst in organic reactions. The structure of this organic-inorganic catalyst has been characterized by N2adsorption-desorption isotherms, and the SEM, EDS, WDX, XRD, TGA, AAS, FT-IR and VSM techniques. This magnetically recyclable catalyst was used in the homoselective synthesis of tetrazole and pyranopyrazole derivatives. This catalyst can be reused several times without significant loss of its catalytic efficiency. The heterogeneity and stability of this nanocatalyst were studied by hot filtration and the AAS technique. Also, the reused catalyst was characterized by the SEM, EDS, AAS and BET techniques.
