Oxidation of allylic and benzylic alcohols to aldehydes and carboxylic acids.
An oxidation of allylic and benzylic alcohols to the corresponding carboxylic acids is effected by merging a Cu-catalyzed oxidation using O2 as a terminal oxidant with a subsequent chlorite oxidation (Lindgren oxidation). The protocol was optimized to obtain pure products without chromatography or crystallization. Interception at the aldehyde stage allowed for Z/E-isomerization, thus rendering ...
متن کاملUltrasound assisted oxidation of various alcohols to corresponding aldehydes by using Al2O3 as catalyst
A convenient approach for oxidation of structurally diverse alcohols has been developed using KMnO4 as oxidant agent in the presence of a catalytic amount of Al2O3 in aqueous acetonitrile. In this method various alcohols generally afforded the corresponding carbonyl compounds directly in good to high yield under ultrasound irradiation conditions. It shows that this kind of catalysis system is v...
متن کاملAllylic and benzylic sp3 C-H oxidation in water.
A copper-catalyzed method for the oxidation of allylic and benzylic sp(3) C-H by aqueous tert-butyl hydroperoxide (T-Hydro) in water using a recyclable fluorous ligand has been developed. The reaction procedure is tolerant to additional functional groups and the fluorous ligand could be reused with little loss of catalytic activity.
متن کاملSelective oxidation of primary alcohols to aldehydes with H5IO6/V2O5 in ionic liquid
An efficient protocol for the selective oxidation of primary alcohols to aldehydes withH5IO6/V2O5 in ionic liquid [bmpy][PF6] has been developed. High yields of the products, mildreaction conditions and simple experimental procedure make this protocol complementary tothe existing methods. The catalyst can be reused for several times without obvious loss of thecatalytic activity.
متن کاملShape-Selective Oxidation of Benzylic Alcohols by a Receptor Functionalized with a Dicopper(II) Pyrazole Complex
A novel metallohost containing a substrate-binding site and two copper ions held by two bis-pyrazole ligand sets is described. The cavity of this molecule can bind dihydroxybenzene guests (association constants in chloroform are in the range K& = 2000-3000 M-1). In the presence of benzylic alcohols the Cu(II) centers of the metallohost are reduced to Cu(I). During this process the alcohols are ...
