Herein, an effective system for vinyl or aryl C(sp 2 )-O bond forming to construct both the ( Z )-2-iodovinyl aryl ethers and diaryl ethers underneath steel-, photocatalyst- and mild-totally free affliction in one particular-phase, has been created. To crank out the two sought after products and solutions, we proposed a S NAr 2 reaction of phenol with vinyl aryl iodonium salts intermediates that subsequently direct to the phenyl-I bond cleavage and phenyl-O bond formation. We to begin with located that the vinyl aryl iodonium salts was shaped in situ from the spiro- cis – β -phenol-VBXs, which was produced in between electrophilic spiro-EBXs and nucleophilic arylols. Tri-substituted alkenes and functionalized diaryl ethers can be afforded from the two desired items.
