“…Crystal structure studies showed that major and minor products are trans-(2) and cis-(3) isomer of [Ru((PPh 2 ) 2 NCH 2 -C 4 H 3 S) 2 Cl 2 ], respectively. The trans isomer, 2 was isolated and characterized by observing a singlet at 78.05 ppm in the 31 P NMR spectrum in line with the values previously observed for similar compounds [41,42]. This indicates that (PPh 2 ) 2 NCH 2 -C 4 H 3 S is acting as a bidendate chelating ligand.…”

Readily available and modular hybrid amine/benzimidazole-based 1H-benzimidazole-2-methanamine (BIMA) ligands in combination with 2,3-O-isopropylidene-2,3-dihydroxy-1,4-bis(diphen-A C H T U N G T R E N N U N G ylphosphino)butane (DIOP) afford efficient catalytic systems for the ruthenium(II)-catalyzed asymmetric hydrogenation (AH) of a number of aryl ketones. The AH proceeds smoothly with substrateto-catalyst (S/C) molar ratios of up to 100,000 (TOF of 6500 h À1 , 8 atm) giving chiral alcohols in up to 99% ee.

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 observed chiral-induction for related systems and allows for hydrogenation to be uncharacteristically conducted in (non-protic) THF solvent. The observed catalyst performance is sensitive to the reaction conditions employed and the particular compounds involved. The origins of such features are considered to derive from the added functionality provided by the tetrazole moiety in 1, which due to its modular nature provides a good basis for further development.
