Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 5402-55-1, Name is 2-Thiopheneethanol, SMILES is OCCC1=CC=CS1, belongs to indole-building-block compound. In a document, author is Tayebee, Reza, introduce the new discover, Product Details of 5402-55-1.
H3PW12O40/SBA-15 for the Solventless Synthesis of 3-Substituted Indoles
A family of silica-supported H3PW12O40 (HPW) solid acid catalysts was prepared by wet impregnation of mesoporous SBA-15 and investigated for the solventless synthesis of 3-substituted indoles under mild conditions. Mesoporous SBA-15 facilitated a high dispersion of immobilised H3PW12O40, significantly improving the catalytic efficiency of the heteropolyacid for the desired multi-component transformation. The yield of 3-substituted indoles strongly correlated with HPW loading (which spanned 3.2-51.6 wt %) and corresponding acid strength; the 51.6 wt % HPW/SBA-15 delivered 81% yield of 2-[(1H-indol-3-yl)(phenyl)methyl]malononitrile, approximately five times greater than that of the unsupported HPW, and exhibited a broad substrate scope for aromatic aldehydes.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 5402-55-1 is helpful to your research. Product Details of 5402-55-1.
