Synthesis of Boron‐Substituted Diaryliodonium Salts and Selective Transformation into Functionalized Aryl Boronates

Abstract

Dormant boron awaits its true destiny in diaryliodonium salts synthesized from aryl boronate derivatives according to two alternative general methods with hypervalent iodine(III) reagents and fluoroalcohol solvents: transformation of an aryl CH bond and boron–iodine(III) exchange (see scheme; FG=functional group). The salts could be functionalized by both catalyst-free and metal-catalyzed reactions without loss of the boron functionality.
