Webα-Amino radicals, from simple tertiary amines, were employed as halogen atom transfer agents in metallaphotoredox catalysis for cross-electrophile couplings of organic bromides with organic iodides. This XAT strategy proved to be efficient for the generations of carbon radicals from a range of partners; alkyl, aryl, alkenyl and alkynyl iodides. http://chem.hust.edu.cn/info/1052/7737.htm
