Abstract: A transition-metal-free and environmentally friendly synthesis method for bromobenzothiazines through tandem C-H amination/bromination was reported. This reaction contains both intramolecular C-H amination and site-selective electrophilic bromination of arenes with NaBr as the bromo source, PhI(OAc)2… read more here.
