Novel bifunctional mesoporous catalysts based on preyssler heteropolyacids for green pyrrole derivative synthesis
(Molecular Diversity Preservation International, 2018-10-26)
In this paper, we report the synthesis of Preyssler heteropolyacids supported on mesoporous alumina in order to obtain materials with acid–base properties. A series of pyrrole derivatives were synthesized using a suitable ...
A Green Nanopalladium-Supported Catalyst for the Microwave-Assisted Direct Synthesis of Xanthones
(Georg Thieme Verlag Kg, 2019-10-30)
We report an efficient, selective, rapid and eco-friendly protocol for the one-step synthesis of a small xanthone library via an intermolecular catalytic coupling from readily available salicylaldehydes and 1,2-dihaloarenes ...
Valorization of Different Wastes and Their Use for the Design of Multifunctional Eco-catalysts
(Springer, 2016-07-25)
The desire to protect the environment for futuregenerations has led to the reutilization of all recoverableand recyclable wastes. Consequently, different residuesfrom various sources were collected to make mixed compoundsto ...
Separation technology meets green chemistry: Development of magnetically recoverable catalyst supports containing silica, ceria, and titania
(2018)
© 2018 IUPAC & De Gruyter.Magnetic separation can be considered a green technology because it is fast, efficient, consumes low energy, and minimizes the use of solvents and the generation of waste. It has been successfully ...

The sulfoxidation reaction catalyzed by CoBr2 complexes, under the magnifying glass of green parameters
(Elsevier B.V., 2018-07)
Different cobalt (II) and nickel (II) species were used as catalysts in sulfoxidation reactions giving excellent yields and high chemoselectivity. Among the cobalt (II) species, both γ-cyclodextrin complexes synthesized ...
Titania-heteropolyacid composites (TiO2-HPA) as catalyst for the green oxidation of trimethylphenol to 2,3,5-trimethyl-p-benzoquinone
(Springer, 2020-02-10)
New catalysts containing phosphomolybdic acid (PMA) and vanadophosphomolybdic acid (VPMA) in a titania matrix were synthesized by the sol–gel process with different heteropolyacid loads (5%, 15%, and 30% (w/w): 5PMA-TiO2, ...
Suitable multicomponent organic synthesis using heteropolycompounds as catalysts
(Bentham Science Publishers, 2015-04)
Nowadays, scientists need to work with non-contaminating technologies. Some approaches include the use of multicomponent reactions (MCRs), and solid and reusable catalysts. Through MCRs it is possible to work without ...
Volcanic ash as reusable catalyst in the green synthesis of 3H-1,5-benzodiazepines
(Walter de Gruyter GmbH, 2019-01-28)
The volcanic ash from the Andes mountain range (Puyehue-Cordon Caulle volcanic complex situated in western South America on the Argentinean-Chilean border) was used as heterogeneous acid catalyst in the suitable synthesis ...
