Abstract
A Bi-catalyzed cross-coupling of arylboronic acids with perfluoroalkyl sulfonate salts enables the unusual construction of C(sp2)-O bonds using commercially available NaOTf and KONf as coupling partners. The reaction is based on a Bi(III)/Bi(V) redox cycle. An electron-deficient sulfone ligand proved to be key for the successful implementation of this protocol.
