Readily available chiral hybrid NH 2 /tetrazole ligand [(S)-TEA, 1] in combination with Ru-BINAP or Ru-DIOP complexes catalyzes the asymmetric hydrogenation of a number of simple ketones with moderate enantioselectivity (up to 72% ee). The tetrazole functionality results in reversal of the typically
