Catalytic 1,2-boron transposition enables precise positional editing of functional groups. A tunable hydrogen-atom transfer mechanism drives site-selective migration for a range of boronate substrates, enabling late-stage modification and a modular three-step platform for the synthesis of various positional isomers of alcohols, amines, acids, alkenes and halides.
