Very low loading and short reaction times are characteristic features of the quantitative reduction of different ketones using 2‐propanol and terdentate [RuX(CNN)(dppb)] (X=H, Cl (see structure); dppb=Ph 2 P(CH 2 ) 4 PPh 2 ) complexes prepared from 6‐(4′‐methylphenyl)‐2‐pyridylmethylamine. The reduction apparently takes place by reversible insertion of the substrate into the RuH bond, thus leading to a Ru II alkoxide.
