2,6-bis(3,5-dimethylpyrazol-1-yl)pyridine: A useful pseudo-N-3 ligand in efficient ruthenium(II)-catalyzed transfer hydrogenation of ketones
TL;DR: In this article, a ruthenium(II) complex bearing the ligand 2,6-bis(3,5-dimethylpyrazol-1-yl)pyridine (Me(4)BPFy) was used for transfer hydrogenation of ketones.
Journal ArticleDOI
Palladium-Catalyzed Regiospecific Aminocarbonylation of Alkynes in the Ionic Liquid [bmim][Tf2N]
Yu Li,Howard Alper,Zhengkun Yu +2 more
TL;DR: Regiospecific construction of 2-substituted acrylamides was achieved by palladium-catalyzed aminocarbonylation of alkynes in the ionic liquid without any acid additive under relatively mild conditions.
Journal ArticleDOI
Copper-Catalyzed Oxidative Arylation of Heteroarenes under Mild Conditions Using Dioxygen as the Sole Oxidant
TL;DR: CuCl could very efficiently catalyze the oxidative cross-coupling between heteroarenes and arylboronic esters with good yields and selectivities and was initiated by using Pd as the catalyst and dioxygen as the oxidant.
Journal ArticleDOI
A Versatile Ruthenium(II)–NNC Complex Catalyst for Transfer Hydrogenation of Ketones and Oppenauer‐Type Oxidation of Alcohols
TL;DR: A ruthenium(II)-NNC pincer complex containing an unsymmetrical tridentate pyrazolyl-pyridyl-tolyl ligand exhibited excellent catalytic activity for the transfer hydrogenation of ketones in 2-propanol at reflux, and for the Oppenauer-type dehydrogenative oxidation of alcohols in acetone atReflux.
Journal ArticleDOI
Efficient catalytic asymmetric synthesis of α-substituted phenyloxyacetyloxy and aroyloxy phosphonates
TL;DR: Optically active α-substituted phenyloxyacetyloxy and aroyloxy phosphonates have been synthesized via catalytic asymmetric hydrogenation of the corresponding prochiral α,β-unsaturated phosphonate using Rh(I)/( R, R )-Me-DuPhos as the catalyst in methanol at 18°C as mentioned in this paper.
