Oxidative C-C Bond Cleavage of Aldehydes via Visible-Light Photoredox Catalysis

The visible-light mediated oxidative C-C bond cleavage of aldehydes has been achieved in good yields at ambient temperature and open to air using Ru(bpy)(3)Cl-2 (bpy = 2,2'-bipyridine) as the photoredox catalyst Moreover, we further demonstrated the application in a tandem Michael/oxidative C C bond cleavage reaction.
