Category: quinoxaline. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1-(Bromomethyl)-4-ethylbenzene, is researched, Molecular C9H11Br, CAS is 57825-30-6, about Synthesis of Isothiochroman-3-ones via Metal-Free Oxidative Cyclization of Alkynyl Thioethers. Author is Zhang, Ying-Qi; Zhu, Xin-Qi; Chen, Yang-Bo; Tan, Tong-De; Yang, Ming-Yang; Ye, Long-Wu.
A novel Bronsted acid-catalyzed oxidative C-H functionalization of alkynyl thioethers has been developed. This method allows the practical synthesis of valuable isothiochroman-3-ones in mostly moderate to good yields under mild reaction conditions and features a broad substrate scope and wide functional group tolerance. Moreover, this metal-free oxidation can also be used to promote formal N-H insertion involving an unexpected 1,2-sulfur migration, affording useful 1,4-benzothiazin-3-ones.
