tris-N-heterocyclic carbene iridium (tris-NHC-Ir, 0.05 mol %) complexes as catalysts and Ba(OH)2 as the base, along with the generation of byproducts water and hydrogen gas. A plausible mechanism involving dehydrogenation of alcohols, aldol-condensation, and 1,2-alkyl rearrangement reactions was proposed, in which 1,2-alkyl rearrangement was responsible for the construction of the quaternary carbon center.
