Stereospecific Synthesis of (Z,Z)‐Isobenzofurans via Radical‐Enabled Cleavage of C(sp3)−C(sp3) and C(sp2)‐Halogen Bonds

A novel radical‐induced annulation/1,8‐halosulfonylation of β‐alkynyl ketones with haloaryl diazonium tetrafluoroborates and DABCO.bis(sulfur dioxide) was first achieved via the cleavage/recombination of C(sp3)−C(sp3) and C(sp2)‐halogen bonds, from which 47 examples of sulfone‐containing 1,3‐dimethy...
