One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 121-79-9, Name is Propyl Gallate, formurla is C10H12O5. In a document, author is Liu, Yi-Wen, introducing its new discovery. HPLC of Formula: https://www.ambeed.com/products/121-79-9.html.
An efficient approach to access functionalized 3-alkenylindoles has been developed through Er(OTf)(3) catalyzed addition of ynamides and indoles. A number of C-aryl substituted ynamides 7a-7k could react with indoles 6a-6s, affording the desired products 8aa-8sa, Bab-8ak, Bbd, 8bk and 8tc in moderate to excellent yields with high regioselectivities.
