Three‐Component C–H Bond Sulfonylation of Imidazoheterocycles by Visible‐Light Organophotoredox Catalysis

Year: 2020

Type: article

Abstract: The first entirely visible‐light photoredox catalyzed sulfonylation of imidazoheterocycles has been developed. This transformation demonstrates an efficient C–H functionalization for the straightforward synthesis of novel C‐3 sulfonylated imidazoheterocycles from various imidazopyridines and diaryliodonium salts with different electronic and steric properties and easy to handle DABCO‐bis(sulfur dioxide). The reaction proceeds in moderate to good yields under mild conditions at room temperature using the inexpensive organophotocatalyst EosinY·Na2 and shows a high functional group tolerance (37 examples).
