Bromides and iodides

WebA bromide is a common saying or proverb that is obvious and not that helpful, like "When life hands you lemons, make lemonade." WebMay 8, 2024 · A metal-free synthesis of aryl bromides and iodides from anilines via halogen abstraction from bromotrichloromethane and diiodomethane is described. This one-pot reaction affords aryl halides from the corresponding anilines in moderate to excellent yields without isolation of diazonium salts.
