Mechanism of the aerobic oxidation of alcohols by palladium complexes of N-heterocyclic carbenes.
Quantum mechanics (B3LYP density functional theory) combined with solvation (Poisson-Boltzmann polarizable continuum solvent model) was used to investigate six mechanisms for the aerobic oxidation of alcohols catalyzed by (NHC)Pd(carboxylate)(2)(H(2)O) complexes (NHC = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene). Of these, we find that "reductive beta-hydride elimination", in which the be...
متن کاملDehydrogenative Coupling of Primary Alcohols To Form Esters Catalyzed by a Ruthenium N-Heterocyclic Carbene Complex
The ruthenium complex [RuCl2(IiPr)(p-cymene)] catalyzes the direct condensation of primary alcohols into esters and lactones with the release of hydrogen gas. The reaction is most effective with linear aliphatic alcohols and 1,4diols and is believed to proceed with a ruthenium dihydride as the catalytically active species. ■ INTRODUCTION T synthesis of an ester is one of the most fundamental tr...
متن کاملOxidation of benzylic alcohols with molecular oxygen catalyzed by Cu3/2[PMo12O40]/SiO2
The aerobic oxidation of alcohols was efficiently completed in high conversion and selectivity using Cu3/2[PMo12O40]/SiO2 as catalyst under mild reaction condition. This reaction provides a new environmentally friendly rout to the conversion of alcoholic function to carbonyl groups.

متن کاملAn insight into the mechanism of the aerobic oxidation of aldehydes catalyzed by N-heterocyclic carbenes.
N-Heterocyclic carbene catalysis for the aerobic oxidation and esterification of aromatic aldehydes was monitored by ESI-MS (MS/MS) and the key intermediates were intercepted and characterized using the charge-tag strategy.
