Solid-state structures of mixed-ligand complexes 9 and 10 were determined by single-crystal X-ray diffraction. Both complexes are unusual in that (NN) over cap' ligands were spontaneously oxidized in air under base-free conditions to give imine-amine bidentate ligands upon replacement of p-cymene by meridional '(NNN) over cap'. The complexes 1-10 were screened for transfer hydrogenation (TH) of aryl ketones with, 2-propanol. The highest catalytic activity was obtained with the :complexes containing tridentate '(NNN) over cap' and 7, which contain nonsulfonated 2-(aminomethyl)pyridine. However, for complexes 6(a-c), containing p-cymene (a facial tridentate ligand), a slower reaction rate was observed.eninfo:eu-repo/semantics/closedAccessAsymmetric Transfer HydrogenationMixed Mu-AcetatoCrystal-StructuresCopper(Ii)MetalPalladium(Ii)EprArticle30154165417310.1021/om200470pQ1WOS:0002933076000312-s2.0-79961089113Q2
