Abstract

In a conceptually novel borylation reaction via a mild photoinduced decarboxylation of redox-activated aromatic carboxylic acids, cheap and easily prepared N-hydroxyphthalimide esters act as the aryl radical precursors. The reaction is operationally simple, scalable, does not require the use of expensive transition metals or ligands and displays broad scope and functional group tolerance.
