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)3Cl2 (bpy = 2,2′-bipyridine) as the photoredox catalyst. Moreover, we further demonstrated the application in a tandem Michael/oxidative C-C bond cleavage reaction.

Enantioselective 1,4-conjugate addition of diethylzinc to (E)-alkenyl aryl ketones catalysed by Cu/DiPPAM complex

We report here the use of the DiPPAM-L1 ligand for copper-catalysed asymmetric conjugate addition (ACA) of diethylzinc to various (E)-alkenyl aryl ketones where the aryl ring is either a phenyl group substituted by nitro, chloro or methoxy groups or not s

Construction of a new type of chiral bidentate NHC ligands: copper-catalyzed asymmetric conjugate alkylation

We synthesized in three steps simple chiral bidentate NHC compounds that carry an achiral coordinating group as N-substituent and revealed that they serve as efficient chiral auxiliaries for the copper-catalyzed asymmetric conjugate addition of dialkylzin
