Abstract: Chiral metal complexes catalyze enantioselective carbonyl propargylation via reductive coupling or as hydrogen auto‐transfer processes, in which reactant alcohols serve dually as reductant and carbonyl proelectrophile. Unlike classical propargylation protocols, which rely on allenylmetal reagents… read more here.

Abstract: Oxidative cross-coupling has developed into a robust method for carbon-carbon (C-C), carbon-heteroatom (C-X), and heteroatom-heteroatom (X-Y) bond formation. Despite considerable advances in this field, the traditional oxidative cross-coupling reactions usually employ stoichiometric amounts of chemical… read more here.
