Synthesis of Ni(II)-3,5-dichloro-2-hydroxybenzenesulfonyl chloride supported SBA-15 and its application as a nanoreactor catalyst for the synthesis of diaryl sulfides via reaction of aryl halides with thiourea or S8

Biochar as heterogeneous support for immobilization of Pd as efficient and reusable biocatalyst in C–C coupling reactions

“…To optimize the Suzuki coupling reaction, the reaction of 4-iodotoluene with PhB(OH) 2 was selected as a model reaction. This model reaction was investigated in the presence of various amounts of Pd(0)-TBA@biochar [5][6][7][8][9][10][11]. Based on the obtained results, PEG-400 as solvent and sodium carbonate (Na 2 CO 3 ) as base gave the best conversion of starting materials to products.…”

“…[1][2][3][4] In this regard, various nanoparticles have also been applied as catalyst supports due to their special properties such as high surface area and insolubility. [8] Therefore, nanoparticles are widely employed as solid supports for heterogenization of homogeneous catalysts.

“…[5][6][7] When the size of particles is decreased, their surface area is increased, which will be lead to high capacity of catalyst loading. [1][2][3][4][5][6][7][8] For example, iron oxide, [9] mesoporous silica materials, [10] carbon nanotubes, [11] ionic liquids, [12] polymers, [13] graphene oxide, [14,15] heteropolyacids, [16] boehmite nanoparticles, [17] etc., have been used as catalyst supports; however, all of these materials require chemical procedures and chemical starting materials for their preparation which are expensive and not environmentally friendly.

A new copper-supported zinc ferrite as a heterogeneous magnetic nanocatalyst for the synthesis of bis(pyrazolyl)methanes and oxidation of sulfides

“…In the spectra of ZnFe 2 O 4 @SiO 2 @APTES@DHBS (d) the peak in the 1327 cm −1 is attributed to the appearance of sulfone groups (-SO 2 -) and the peaks in the 1425 and 1605 cm −1 correspond to the carbon-carbon double bond (C=C) in the aromatic ring. Moreover, a certain band in the 3437 cm −1 is due to aromatic O-H 45 . In Fig.…”

Effect of Time, Temperature and Stirring Rate Used in the First Step of the Synthesis of SBA-15 on Its Application as Reductor of Tars in Tobacco Smoke

“…The SBA-15 is a mesoporous material with promising properties, and it has been employed for multiples applications such as adsorption [19], storage [20], support, and catalysis [21,22]. In addition, novel applications for this material have been developed in recent years, for example, as a support in oxidative desulfurization processes [23], support in the synthesis process of stilbene and chalcone derivatives with biological activity against influenza A virus by self-, cross-, and rig-closing metathesis procedures [24], or support of palladium catalysts in methane combustion and NOx reductions [25].…”
