文摘

A new pentamethylcyclopentadienyl-functionalized N-heterocyclic carbene ligand (Cp*-NHC^Me) has been prepared and coordinated to iridium upon reaction with [Ir(μ-Cl)(cod)]₂. The chiral Ir complex is obtained as a racemic mixture of the two possible enantiomers, and its crystal structure is described. The new compound shows high catalytic activity toward transfer hydrogenation, β-alkylation of secondary alcohols with primary alcohols, and amination of primary alcohols.
