Asymmetric transfer hydrogenation of ketones using Ru(0) nanoparticles modified by Chiral Thiones

Applied Organometallic Chemistry (2019)

Noor U Din Reshi Dineshchakravarthy Senthurpandi Ashoka G. Samuelson

The catalytic asymmetric transfer hydrogenation (ATH) of acetophenone in isopropanol by Ru(0) nanoparticles (NPs) obtained by the in‐situ reduction of Ru (II) half‐sandwich complexes of chiral 2‐oxazolidinethiones and 2‐thiozolidinethiones was examined and compared with the catalytic activity of Ru(0) NPs formed in‐situ by the reduction of [Ru( p‐ cymene)(Cl) 2 ] 2 in presence of optically active ligands such as (S)‐4‐isobutylthiazolidine‐2‐thione, (S)‐4‐Isopropyl‐2(−2‐pyridinyl)‐2‐oxazoline, (8S, 9R)‐(−)‐cinchonidine, (S)‐leucinol, (S)‐phenylalaninol, and (S)‐leucine. Three of the best catalytic systems were then examined for ATH of thirteen aromatic ketones with different electronic and steric properties. A maximum of 24% ee was obtained using NPs generated from the Ru (II) half‐sandwich complex with (S)‐4‐isobutylthiazolidine‐2‐thione in the TH of acetophenone. The NPs were characterized by TEM and DLS measurements. Kinetic studies and poisoning experiments confirmed that the reaction is catalyzed by the chiral NPs formed in‐situ . Complete characterization of the complexes, including the X‐ray crystallographic characterization of two complexes, was also carried out.

B–H Bond Activation in a Rh(III) Hydrido Borohydride Complex [Rh(H)(K²-BH₄)^tBu4(PNCNP)] Gives a Rh(I) σ-Dihydrogen Complex [Rh(η²-H₂)^tBu4(PNCNP)]: An Experimental and Theoretical Study

Rh(III) pincer hydrido chloride and borohydride complexes [Rh(H)CltBu4(PNCNP)] (1) [tBu4(PNCNP) = 2,6-bis((di-tert-butylphosphaneyl)amino)benzen-1-ide] and [Rh(H)(K2-BH4)tBu4(PNCNP)] (2) have been synthesized and characterized. Heating the [Rh(H)(K2-BH4)tBu4(PNCNP)] complex (2) at 336 K in tetrahydrofuran (THF) afforded the Rh(I) σ-H2 complex, [Rh(η2-H2)tBu4(PNCNP)] (3), and H3B·THF via the B–H bond activation of the borohydride. The [Rh(η2-HD)tBu4(PNCNP)] (3-HD) isotopomer was also prepared by heating the [Rh(H)(K2-BD4)tBu4(PNCNP)] complex (2-BD4) at 336 K in THF. The formation of [Rh(η2-H2)tBu4(PNCNP)] (3) was established using 1JH,D coupling constant and variable temperature spin–lattice relaxation time measurements and supported by density functional theory (DFT) calculations. At 273 K, the [Rh(η2-H2)tBu4(PNCNP)] complex (3) reverted back to the [Rh(H)(K2-BH4)tBu4(PNCNP)] complex (2) upon reaction with H3B·THF. The [Rh(η2-H2)tBu4(PNCNP)] complex (3) was also obtained independently by two alternative routes. The reaction of [Rh(η2-H2)tBu4(PNCNP)] (3) with N2 at 273 K afforded the [Rh(N2)tBu4(PNCNP)] complex (4); this reaction was found to be reversible. The reaction of [Rh(η2-H2)tBu4(PNCNP)] (3) with CH3CN, CO, and O2 occurred instantaneously and yielded the corresponding products [Rh(CH3CN)tBu4(PNCNP)] (5), [Rh(CO)tBu4(PNCNP)] (6), and [Rh(η2-O2)tBu4(PNCNP)] (7), respectively. These observations together with computational studies showed that the binding strengths of CH3CN, CO, and O2 with the Rh center are significantly greater than those of H2 and N2.
