Synthesis of C1‐Symmetric BINOLs Employing N‐Heterocyclic Carbene–Copper Complexes

Fucntionalizing BINOL: Bis‐NHCCu complexes can be used for the oxidative coupling of 2‐naphthols. Product yields are highest when using electron‐deficient 2‐naphthols. Mixed couplings between electron‐rich and electron‐poor 2‐naphthols can be conducted to give good yields of the mixed products....
