phosphoranyl radical chemistry allows for precise cleavage of a stronger C-O bond and formation of a weaker C-Cbond by 1,5-aryl migration under mild reaction conditions. This new protocol is independent of substrate redox-potential, electronic, and substituent effects. It affords a general and promising access to 60 examples of synthetically versatile o-amino and o-hydroxy diaryl ketones under redox-neutral
