An inert, rigid chiral-at-metal iridium(III) complex enables a highly efficient catalytic asymmetric transfer hydrogenation of β,β-disubstituted nitroalkenes. The catalysis does not involve any direct metal coordination but operates exclusively through weak interactions with functional groups properly arranged in the ligand sphere of the iridium complex.
