New Advances in Chemical Research in 2021. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. The reactant in an enzyme-catalyzed reaction is called a substrate. 14814-09-6, Name is 3-Mercaptopropyltriethoxysilane, molecular formula is , belongs to benzoxazole compound. In a document, author is Yao, Zhenyu, Formula: https://www.ambeed.com/products/14814-09-6.html.
As balanced electron-rich P,C-chelating ligands, phosphine-phosphonium-ylides are considered for their ability to in situ promote palladium-catalysed direct C(sp(2))-H arylation. Using methyl phosphonium salts of 2,2′-bis(diphenylphosphino)-1,1′-binaphtyl (methyl-BINAPIUM) as ylide precursors under optimized reaction conditions, arylation of benzoxazole was found to proceed in moderate to high yield to give functional 2-aryl benzoxazoles. A strong anion effect of the non-salt free ylide was evidenced (TfO > I > PF6 approximate to salt-free). This first example of phosphonium ylides as ligands in catalytic C-H activation extends the prospect of their general implementation in homogeneous transition metal catalysis.
