I found the field of Chemistry very interesting. Saw the article Synthesis of 1,4-Benzothiazines via KI/DMSO/O-2-Mediated Three-Component Oxidative Cyclization/Coupling published in 2020. COA of Formula: C8H7NO3, Reprint Addresses Zhao, JW; Xu, JX (corresponding author), Guangdong Med Univ, Sch Pharm, Dongguan 523808, Peoples R China.. The CAS is 100-19-6. Through research, I have a further understanding and discovery of 1-(4-Nitrophenyl)ethanone
A three-component transition-metal-free aerobic method for the generation of 1,4-benzothiazines is reported herein. The KI/DMSO/O-2 system was found to be effective for the oxidative cyclization/coupling of 2-aminobenzenethiols, anilines, and methylketones. Hence, various structurally important imino 1,4-benzothiazines were assembled with broad functional group tolerance. Mechanistic studies revealed an initial oxidation of ketone alpha C-H bonds by the KI/DMSO/O-2 oxidative system.
Welcome to talk about 100-19-6, If you have any questions, you can contact Zhao, JW; Luo, ZG; Xu, JX or send Email.. COA of Formula: C8H7NO3
