Abstract: A sulfonylation reaction of 4-substituted Hantzsch esters, DABCO·(SO2)2, and electron-deficient alkenes at room temperature in the presence of photoredox catalysis under visible light irradiation is described. Not only (E)-chalcones but also (vinylsulfonyl)benzene and 2-vinylpyridine are… read more here.
