A practical and efficient method for the synthesis of alcohols in one pot from readily available alkynes via a tandem process by formic acid promoted hydration and metal-ligand bifunctional iridium-catalyzed­ transfer hydrogenation under mild conditions has been described. This transformation is simple, efficient, and can be performed with a variety of alkynes in good yields and with excellent stereoselectivities. Experimental results showed high catalytic activity, and turnover frequency (TOF) up to 25000. Importantly, this transformation can be conducted in water, and is thus green and environmentally friendly.

Donor Source

A mild catalytic asymmetric transfer hydrogenation of a series of α-amino β-keto ester hydrochlorides catalyzed by a rhodium(III) complex is reported. The use of the formic acid/triethylamine system as the hydrogen donor source provided the corresponding anti and syn amino alcohols with complete conversions, fair diastereoselectivities (up to 97:3 dr), and high enantioselectivities (ee up to >99%).

Electron Withdrawing Substituents

The diruthenium(0) complex [Ru2(µ-CO)(CO)4(µ-dppm)2] (1) (dppm = Ph2PCH2PPh2), is a catalyst for the transfer hydrogenation, using formic acid as hydrogen donor, of the alkynes PhCºCPh, PhCºCMe, EtCºCEt, and PrCºCPr but not of the terminal alkynes HCºCH, PhCºCH, BuCºCH, or the alkynes containing one or two electron-withdrawing substituents PhCºCCO2Me and MeO2CCtriple bondCCO2Me. In the successful reactions, the formic acid is first decomposed to carbon dioxide and hydrogen, which then hydrogenates the alkynes in a slower reaction. In the unsuccessful reactions, the decomposition of formic acid is strongly retarded by the alkyne. In the case with the alkyne PhCºCH, it is shown that the alkyne reacts with protonated 1 to give first [Ru2(µ-CPh=CH2)(CO)4(µ-dppm)2][HCO2], which then isomerizes to give the catalytically inactive, stable complex [Ru2(µ-CH=CHPh)(CO)4(µ-dppm)2][HCO2]. This complex has been structurally characterized and both of the µ-styrenyl complexes are shown to be fluxional in solution.Key words: ruthenium, hydrogenation, catalysis, binuclear..
