A complete switch of regioselectivity in the aminobromination of olefins is realized from delicate changes in the reaction temperature from 25 °C to 40 °C and the atmosphere from air to argon, under catalyst‐free conditions. The resulting α‐bromoamides can be transformed easily to high‐value compounds (e.g., Clobenzorex). Mechanistic studies revealed that the reaction went through a radical pathway
