DOI: 10.1021/acs.orglett.2c00691
Abstract: Two one-pot procedures for the construction of O- and N-bridged diaryliodonium triflates are described. An effective aryne-mediated arylation of o-iodophenols and -sulfonamides provides diarylether and diarylamine intermediates, which are subsequently oxidized and cyclized to the… read more here.

DOI: 10.2174/1385272824999200507124328
Abstract: Due to similar reactivity in comparison with aromatic organometallic reagents, diaryliodonium salts are currently in broad usage as less toxic, highly efficient, stable and mild electrophilic reagents in organic synthesis. The hypervalent iodine center of… read more here.
