2-(Aminomethyl)pyridine−Phosphine Ruthenium(II) Complexes: Novel Highly Active Transfer Hydrogenation Catalysts
TL;DR: In this article, RuCl2(PPh3)3 and RuClCl2[Ph2P(CH2)4PPh2]-with 2-(aminomethyl)pyridine (ampy) displacement were used to obtain the isomer cis-cis-RuCl2pPh32(ampy), which has been proven to be a good precursor for the preparation of the complexes cis-Rucl2(PP)(ampy).

TL;DR: Ruthenium cis -dichloro complexes with matched chiral diphosphane and aminopyridine ligands are highly active catalysts for the transfer hydrogenation of ketones, affording turnover frequencies of up to 70 000 h -1 at 60 ° C and ee values up to 99 %.

Fast and Chemoselective Transfer Hydrogenation of Aldehydes Catalyzed by a Terdentate CNN Ruthenium Complex [RuCl(CNN)(dppb)]
TL;DR: In this paper, aromatic, aliphatic and α,β-unsaturated aldehydes are quickly, quantitatively and chemoselectively reduced to primary alcohols with 2-propanol using 0.05-0.01 mol% of the terdentate CNN ruthenium complex RuCl(CNN)(dppb) in the presence of potassium carbonate (K 2 CO 3 ; 1-10 mol%) as a weak base.

Osmium(II) CNN Pincer Complexes as Efficient Catalysts for Both Asymmetric Transfer and H2 Hydrogenation of Ketones.
TL;DR: In this paper, the first CNN pincer osmium catalysts are described, which demonstrate high catalytic activity and productivity in the reduction of ketones by either TH or HY (TOF and TON up to 10 6 h 1 and======10 5, respectively).

Chiral and nonchiral [OsX2(diphosphane)(diamine)] (X: Cl, OCH2CF3) complexes for fast hydrogenation of carbonyl compounds.
TL;DR: Different ketones, including alkyl aryl, bulky tert-butyl, and cyclicketones, have successfully been hydrogenated with enantioselectivities up to 99% and with S/C ratios of 5000-100,000 and TOFs of up to 4.1 x 10(4) h(-1) at 60 degrees C.
