Dormant boron awaits its true destiny in diaryliodoniumsalts synthesized from aryl boronate derivatives according to two alternative general methods with hypervalent iodine(III) reagents and fluoroalcohol solvents: transformation of an aryl CH bond and boron–iodine(III) exchange (see scheme; FG=functional group). The salts could be functionalized by both catalyst‐free and metal‐catalyzed reactions
