A clean and highly efficient alcohol oxidizing system, using hydrogen peroxide in the presence of CuCl 2/Bifunctional ionic liquid (CuCl 2/BIL), under solvent free condition has been developed. The oxidation proceeds smoothly with 0.01 mmol of CuCl 2/BIL and 30% of H 2O 2 to give the carboxylic acids with excellent yield. Especially, this green reaction also exemplifies advances toward the synthesis of aliphatic and aromatic acid from the corresponding alcohol. The advantages of the present protocol include solvent free condition, wide functional group tolerance and convenient product isolation. The BIL can be recycled and reused for five runs without any significant loss of its activity. © 2012 Elsevier B.V. All rights reserved.

A novel, effective asymmetric 1-glycyl-3-methyl imidazolium chloride-iron(III) [[Gmim]Cl-Fe(III)] complex was synthesized and studied as organocatalyst in asymmetric aldol addition under solvent free condition at 25 C. The hydrophobic group of amino acid favors reagent diffusion toward the chloroglycine moiety increasing the catalytic activity of supported iron complex. This method contains simplified product isolation and catalyst recycling, affording substituted aromatic aldehydes imparting high yield of aldol with excellent stereo-selectivity. This recyclable heterogeneous catalyst provides a simple strategy for the generation of a variety of new CC bonds under environmentally benign condition. © 2013 Elsevier B.V.

Direct oxidation of primary alcohols to the corresponding carboxylic acids is performed highly efficiently at room temperature with anhydrous tert-butyl hydroperoxide in the presence of a catalytic amount of easily available CuCl under ligand free conditions in acetonitrile. Benzylic alcohols are more reactive than aliphatic alcohols, and these benzylic alcohols are selectively oxidized to the corresponding acids in the presence of aliphatic alcohols such as 1-octanol and 1-decanol. © 2008 Elsevier Ltd.

CuCl catalyzed selective oxidation of primary alcohols to carboxylic acids with tert-butyl hydroperoxide at room temperature

Oxidation of aldehydes to the corresponding carboxylic acids can be performed highly efficiently at room temperature with 70% tert-butyl hydroperoxide (in water) in the presence of a catalytic amount of easily available ligand free CuCl in acetonitrile as solvent under very mild conditions. This oxidation protocol works well for various aldehydes including aliphatic aldehydes and aliphatic dialdehydes. © 2007 Elsevier Ltd. All rights reserved.
