Advances in Decarboxylative Oxidative Coupling Reaction

The Journal of Organic Chemistry, 2018
Since carboxylic acid derivatives are commercially available, nontoxic, cheap, and normally stable to air and moisture, carboxylic acid derivatives are ideal reactants for synthetic strategy. In recent years, decarboxylative oxidative coupling reactions, which normally involve direct C-H bond activation, have attracted more and more interest from the ...

Oxidative decarboxylation of diclofenac by manganese oxide bed filter

Water Research, 2013
Diclofenac (DCF) was eliminated by fast chemical oxidation on natural manganese oxide in a column reactor. Identification of transformation by-products of DCF by HPLC-UV-MS(n) gave evidence of decarboxylation, iminoquinone formation and dimerization.

Oxidative Decarboxylation of Carboxylic Acids

Russian Chemical Reviews, 1980
The present state of studies on the decarboxylation of carboxylic acids by various oxidation systems is described and the dependence of the yield and composition of the reaction products on the structure of the carboxylic acid, the type of oxidant and its ligand environment, the nature of the solvent, and the reaction mechanism is considered.

Decarboxylation of Oxidized Single-Wall Carbon Nanotubes

Journal of Nanoscience and Nanotechnology, 2007
A classical protocol widely used in organic chemistry of aromatic and polyaromatic molecules has been successfully applied in this work for the decarboxylation of oxidized single-wall carbon nanotube (SWNT) to rend C-H SWNT derivatives. SWNT produced by arc discharge method have been oxidized during a purification process using strongly oxidant agents,

Photoredox‐Catalyzed Decarboxylative Oxidation of Arylacetic Acids

Chemistry – An Asian Journal, 2018
AbstractA photoredox‐catalyzed decarboxylative oxidation of arylacetic acids, which are privileged scaffolds in pharmaceuticals, is reported herein. The established method is operationally simple and a variety of substrates are applicable, providing rapid access to dehomologated bioisosteres of common pharmaceuticals.

Oxidative decarboxylation of cyclohexanecarboxylic acid

Recueil des Travaux Chimiques des Pays-Bas, 1963
AbstractCyclohexanecarboxylic acid is converted to a mixture of cyclohexanone and cyclohexene by reacting it at temperatures around 200° with an oxygen‐containing gas and steam in the presence of metal‐salt catalysts.

Oxidative Decarboxylation of Podocarpic Acid Derivatives

Australian Journal of Chemistry, 1998
The radical decarboxylation–sulfoxide cycloelimination of 2'-pyridylthio esters formed from a series of podocarpic acid derivatives gives ?4(18) -alkenes in high yield. An exception is the 13-nitro acid (2) which affords a thiohydroxamic ester (28), the relative stability of which is attributed to inhibition of the radical chain reaction by the nitro ...

Oxidative decarboxylation of unsaturated fatty acids

European Journal of Lipid Science and Technology, 2011
Long-chain internal olefins were prepared by silver(II)-catalyzed oxidative decarboxylation of unsaturated fatty acids by sodium peroxydisulfate. Similar to saturated carboxylic acids, 1-alkenes were the major decarboxylation product in the additional presence of copper(II), whereas in the absence of copper(II) alkanes were predominantly formed.

Alkenes from acids by oxidative decarboxylation

Tetrahedron, 1968
Abstract Primary and secondary acids can be readily decarboxylated to alkenes by PbIV tetraacetate in the presence of catalytic amounts of cupric acetate. Terminal alkenes are formed quantitatively from primary acids, but conversions are limited by competitive decarboxylation of acetate.
