TLDR
In this paper, an efficient, environmentally benign method for the preparation of esters from alcohols under mild, neutral conditions without the need for carboxylic acid derivatives and condensing agents was developed.Abstract:
An efficient, environmentally benign method for the preparation of esters from alcohols under mild, neutral conditions without the need for carboxylic acid derivatives and condensing agents was developed. Catalyst design, based on new Ru(II) hydrido carbonyl complexes incorporating electron-rich PNP and PNN ligands has resulted in the novel complex (I) which is an outstanding catalyst for the dehydrogenation of primary alcohols to esters and H2 under neutral conditions.read more

Reactions of benzene based half sandwich ruthenium(II) complex with 2,6-bis((phenylseleno)methyl)pyridine: Preferential substitution of ring resulting in a catalyst of high activity for oxidation of alcohols
TL;DR: In this paper, a pincer ligand complex was synthesized by reacting PhSe− (in situ generated) with 2,6-bis(chloromethyl)pyridine, which reacts with [{(η6-C6H6)RuCl(μ-Cl)}2] (2:1 molar ratio) by preferential substitution of ring resulting in the first Ru-(Se, N, Se) pincers complex, mer-[Ru(CH3CN)2Cl(L)][PF6]( 1 ).H2

TL;DR: In this article, the bidentate HCNN dicarbonyl ruthenium complexes trans,cis-[RuCl2(HCNN)(CO)2] (1−3) and trans, cis-[ RuCl2ampy)(CO] (2]-3] were obtained from the reaction of RuCl3 hydrate with HCO2H and 2-(aminomethyl)pyridine (ampy) ligands.

Direct Condensation of Carboxylic Acids with Alcohols Catalyzed by Hafnium(IV) Salts
TL;DR: It is shown that the direct condensation of equimolar amounts of carboxylic acids and alcohols can be achieved with the use of hafnium(IV) salts, such as commercially available ha fnium( IV) chloride and hafnia(IV), which may be suitable for large-scale operations.

Electron-Rich, Bulky Ruthenium PNP-Type Complexes. Acceptorless Catalytic Alcohol Dehydrogenation
TL;DR: In this article, the electron-rich, bulky tridentate PNP ligand (2,6-bis-(di-tert-butylphosphinomethyl)pyridine) with Ru(PPh3)3Cl2 at 65 °C resulted in formation of a solution containing the dinitrogen monomeric Ru(II) complex 1a and the N2-bridged dinuclear Ru(2) complex 2, which can be interconverted.
