Chem}, title = {Exploring Mn+/Silicalite-1 As A Catalyst For Biginelli Reaction To Produce Dihydropyrimidinone Derivatives}, keywords = {Mn+/Silicalite-1, DHPM Derivatives, Biginelli Reaction, Green Catalyst.}, abstract = {A series of Mn+/silicalite-1 was prepared to be used as a Lewis acid heterogeneous catalyst for a one-pot multicomponent Biginelli reaction. The catalysts were characterized by FTIR, XRD, NH3-TPD, and BET. The mesoporous catalysts possess a pore diameter of 13.83 nm (138.3 {\AA}), a surface area of 282.43 m2/g, and a pore volume of 0.98 cm3/g, which can facilitate the transport of reactants and products smoothly during the catalytic process. Besides the acidity of the catalyst, the maximum temperature of NH3-desorption plays an important role in the catalytic activity. Cr3+/silicalite-1 showed the most active catalyst, while Zn2+/silicalite-1 showed the most selective one. Besides DHPM derivatives as a major Biginelli product, C6-styril of DHPM and Knoevenagel products were isolated if the reaction was conducted using Cr3+/- and Fe3+/silicalite-1. Catalyst Cr3+/silicalite-1 can be used to produce DHPM attaching various substituents and showed a green catalyst potential due to its reusability capacity}, issn = {0976-0083}, url = {https://repository.unigoro.ac.id/id/eprint/4854/}, author = {Hery Suwito, Suwito and Lutfan Zulianto, Zulianto and Kautsar Ul Haq, Haq and Abdulloh, Abdulloh and Erwanto, Erwanto and Fitria Pebriani, Pebriani and Arjun N.
