In situ oxidation of the GaI compound NacNacGa by either N2O or pyridine oxide results in the generation of a labile monomeric oxide, NacNacGa(O), which can easily cleave the C−H bonds of aliphatic and aromatic substrates featuring good donor sites. The products of this reaction are gallium organyl hydroxides. DFT calculations show that these reactions start with the formation of NacNac‐Ga(O)(L) adducts,...
Catalytic enantioselective directed methylene C(sp3)−H amidation reactions of 8‐alkylquinolines using a Cp*RhIII/chiral carboxylic acid (CCA) hybrid catalytic system are described. A binaphthyl‐based chiral carboxylic acid efficiently differentiates between the enantiotopic methylene C−H bonds, which leads to the formation of C−N bonds with good enantioselectivity.
