Ma, Jiliang; Peng, Xinwen; Zhong, Linxin; Sun, Runcang published an article in 2018, the title of the article was Sulfonation of carbonized xylan-type hemicellulose: a renewable and effective biomass-based biocatalyst for the synthesis of O- and N-heterocycles.HPLC of Formula: 5301-96-2 And the article contains the following content:

The application of biomass-based carbonaceous solid acids in catalysis is attracting increasing attention in the field of chem. In this study, a heterogeneous carbon-based solid acid biocatalyst (CXH-SO3H) with regular spherical structure was synthesized from xylan-type hemicellulose (XH) by a simple two-step method. The catalyst was successfully applied in the synthesis of O- and N-heterocycles with yields of 80-99% and 60-97%, resp. In view of environment and economy, CXH-SO3H shows the merits of environmental friendliness, easy operation, simple work-up, excellent yields, and the avoidance of use of organic solvents and expensive catalysts. Moreover, the as-synthesized solid acid catalyst could be used for several cycles without significant loss in its catalytic activity. The results of FT-IR, XRD, and SEM showed that no distinct differences in physico-chem. structures of CXH-SO3H were observed Thus, the eco-friendly CXH-SO3H catalyst is a promising candidate for green synthesis of O- and N-heterocycles from low-cost feed-stocks and has good prospect in partially substituting com. available solid and liquid acid catalysts and precious metal catalysts. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).HPLC of Formula: 5301-96-2

On February 20, 2011, Lee, Seokjoon published an article.Synthetic Route of 5301-96-2 The title of the article was Synthesis of 10β-substituted triazolyl artemisinins and their growth inhibitory activity against various cancer cells. And the article contained the following:

A library of 10-triazolylartemisinins was established comprising compounds that strongly inhibit the growth of cancer cell lines, such as DLD-1, U-87, Hela, SiHa, A172, and Bi1. These compounds were synthesized by an acid-catalyzed reaction of dihydroartemisinin (I) with various triazoles in CH2Cl2 at room temperature In particular, when 3 equivalent of triazole were reacted with I, 10β-(4-substituted triazolyl)artemisinins were obtained, which means that the type of product obtained differs according to the quantity of triazole reactant employed in the synthesis. From the viewpoint of antiproliferative activity against the various cancer cells, compounds, which have a (pentylphenyl)triazole moiety, exhibited potent activity. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Synthetic Route of 5301-96-2

On August 14, 2020, Yadav, Chetna; Maka, Vijay Kumar; Payra, Soumen; Moorthy, Jarugu Narasimha published an article.Recommanded Product: 5301-96-2 The title of the article was De Novo Access to SO3H-Grafted Porous Organic Polymers (POPs@H): Synthesis of Diarylbenzopyrans/Naphthopyrans and Triazoles by Heterogeneous Catalytic Cyclocondensation and Cycloaddition Reactions. And the article contained the following:

Covalent polymerization of contrived mol. building blocks leads to porous organic polymers (POPs) with intrinsic. Leveraging the results of our extensive investigations with mol. systems based on twisted biaryl scaffold as applied to metal-organic frameworks (MOFs) and organic light-emitting diodes (OLEDs), we envisioned that the Fridel-Crafts polyalkylation of the 2,2′,6,6′-tetramethylbiphenyl core with α,α’-dichloro-p-xylene should lead to a hypercrosslinked polymer with assured porosity. Furthermore, sulfonation of the latter in a postsynthetic fashion was surmised to yield a POP grafted with sulfonic acid groups for catalysis. Indeed, the polyalkylation of tetramethylbiphenyl led to a highly porous POP (MeBP) with a BET surface area of 1277 m2 g-1. Also, its sulfonated derivative (MeBP@H) exhibited a surface area of 766 m2 g-1, as determined by N2 sorption anal. Polymer MeBP@H with palpable porosity and endowed with Bronsted acid sites installed through sulfonation was explored for the heterogeneous catalysis of cyclocondensation and cycloaddition reactions in a recyclable fashion. We show that MeBP@H exhibits exceptionally high catalytic activity in the synthesis of a wide variety of photochromic diarylbenzopyrans/naphththopyrans and pharmacol. relevant triazoles at room temperature Diverse functional groups are shown to be tolerated in both condensation and cycloaddition reactions. The catalyst is found to be efficient for the synthesis of triazoles having both electron-rich and electron-poor functionalities. Although a variety of methods are known in the literature for the synthesis of both diarylbenzopyrans/naphthopyrans and triazoles, MeBP@H allows the reactions to be conducted in shorter reaction times and very cleanly, leading to the isolation of products with high operational simplicity. The catalyst can be isolated back by filtration and recycled; indeed, MeBP@H is shown to be recycled for at least 10 catalytic cycles for both reactions without any loss of efficiency. Addnl., MeBP and MeBP@H are found to exhibit higher uptake capacities for CO2 and C2H2 over N2 at 298 K and inverse uptake capacity for C2H2 over CO2. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Recommanded Product: 5301-96-2

Kim, Ji Dang; Palani, Thiruvengadam; Kumar, Manian Rajesh; Lee, Sunwoo; Choi, Hyun Chul published an article in 2012, the title of the article was Preparation of reusable Ag-decorated graphene oxide catalysts for decarboxylative cycloaddition.Related Products of 5301-96-2 And the article contains the following content:

In this study, we demonstrated a noble Ag-decorated graphene oxide catalyst (GOSH-Ag) for use in the decarboxylative cycloaddition reaction. The catalyst was easily prepared by depositing Ag nanoparticles on thiolated graphene oxide (GOSH) surfaces. Transmission electron microscopy (TEM) indicated that the nanoparticles were well-dispersed and of a small, approx. 3.7 nm average size. These characteristics resulted in a high surface area, which enhanced the catalytic activity of the supported catalyst. Moreover, it was found that the aggregation of Ag catalysts was inhibited by the strong adhesion between the GOSHs and the Ag nanoparticles during the chem. reactions, thereby permitting their reuse. Indeed, the supported catalyst could easily be separated and recovered from the reaction mixture and reused several times. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Related Products of 5301-96-2
