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

Acetals from primary alcohols with the use of tridentate proton responsive phosphinepyridonate iridium catalysts
Apurba Ranjan Sahoo,F. Jiang,Christian Bruneau,Gunjan Sharma,Surisetti Suresh,Mathieu Achard +5 more
TL;DR: The association of the new phosphinepyridonate ligands along with an iridium metallic precursor resulted in the selective acetalization of various primary alcohols via a formal dehydrogenative coupling reaction.

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.
