Pd–4,6-Diamino-2-pyrimidinethiol Complex Supported on SBA-15 as a Useful and Retrievable Catalyst for Suzuki–Miyaura and Stille C–C Coupling Reactions

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

“…[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.

“…[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.

Palladium Nanoparticles Supported on Porous Silica Materials as Heterogeneous Catalysts of C−C Coupling and Cross‐Coupling Reactions

“…Palladium deposition was made by treatment with Pd(OAc) 2 (ethanol, reflux, 24 h) and then reduction was performed with NaBH 4 . [84] The catalyst with a Pd loading of 18 wt% (Pd 0 -18-SBA-15) was characterized by appropriate instrumental methods (FT-IR, XRD, TGA). According to TEM and SEM analysis, the morphology of the support did not change upon functionalization.…”

l-Methionine-Zr complex supported on magnetic ZnFe2O4 as a novel, green, and efficient heterogeneous magnetic nanocatalyst for the synthesis of 1H-tetrazole and polyhydroquinoline derivatives

“…14,[26][27][28][29] In comparison with homogeneous catalysts, heterogeneous catalysts have been exclusively studied because of their easy recovery and separation from the reaction mixture. [30][31][32] The use of magnetically separable catalysts is a well-favored and fascinating strategy to bridge the gap between heterogeneous and homogenous catalytic processes. As a main member of the ferrite family, ZnFe 2 O 4 is a promising potential for use as a novel catalytic support.…”
