Chromium(V) oxidations of organic compounds

Oxydation de composes organiques (diacides carboxyliques, hydroxy- et cetoacides, alcools, aldehydes et divers) par le complexe bis-[ethyl-2 hydroxy-2 butanoato (2-)] oxochromate(V) de sodium

The chromic acid oxidation of oxalic acid : Evidence of chromium(IV) oxidation

Abstract In the chromic acid oxidation of oxalic acid in the range where the reaction is first order in the substrate, oxalic acid is very reactive toward chromium(IV) and rather unreactive toward chromium(V). A mechanism analogous to that of the chromic acid oxidation of alcohols and aldehydes is proposed for the first order kinetic term.

A new CrV doping agent for polarized targets

Abstract Proton dynamic polarization in excess of 70% has been obtained in a first test of a new Cr V complex which can be isolated in a pure, stable form.
