SDS of cas: 2402-95-1. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 2-Chloropyridine 1-oxide, is researched, Molecular C5H4ClNO, CAS is 2402-95-1, about Bronsted Acid-Catalyzed Oxygenative Bimolecular Friedel-Crafts-type Coupling of Ynamides. Author is Patil, Dilip V.; Kim, Seung Woo; Nguyen, Quynh H.; Kim, Hanbyul; Wang, Shan; Hoang, Tuan; Shin, Seunghoon.
A non-metal approach for accessing α-oxo carbene surrogates for a C-C bond-forming bimol. coupling between ynamides and nucleophilic arenes was developed. This acid-catalyzed coupling features mild temperature, which is critical for the required temporal chemoselectivity among nucleophiles. The scope of nucleophiles includes indoles, pyrroles, anilines, phenols and silyl enolethers to afford the corresponding functionalized products, e.g., I. Furthermore, a direct test of SN2′ mechanism has been provided by employing chiral N,N’-dioxides which also enlightens the nature of the intermediates in related metal-catalyzed processes.
