Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. Introducing a new discovery about 127956-11-0, Name is Methyl 4-oxotetrahydro-2H-pyran-3-carboxylate, 127956-11-0.
The development of a lead-mediated alpha-arylation reaction between aryl azides and beta-ketoesters or gamma-lactams that facilitates the formation of 3H-indoles is disclosed. Twenty-five examples are included which demonstrate the generality of this reaction to access aryl azides bearing tetrasubstituted o-alkyl substituents. When paired with a Staudinger reduction, this reaction streamlines the synthesis of functionalized 3H-indoles.
Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 127956-11-0 is helpful to your research. 127956-11-0
