More Information
Summary:The invention concerns a method for controlled oxidation of a substituted hydrocarbon substrate, consisting in contacting said substituted hydrocarbon substrate with a source of oxygen in the presence of at least a catalyst selected among those whereof the active phase is obtained from a heteropolyacid of formula (I): Hf[CcDdEeOx] in which: C represents Mo and/or W; D represents phosphorus, arsenic, antimony, silicon, germanium and/or boron; E represents an element selected among vanadium optionally in combination with at least a metal of columns VA, VIIA, VIII or chromium; x being the oxygen number required to observe valences; A represents at least a monovalent cation; B represents VO<2+>, VO<3+>, an ion of an alkaline-earth metal or of one metal of columns VIIA, VIII, IB, IVB and VB of the periodic table of elements; f = a + alpha b with alpha being the ion B charge, i.e. equal to 2, 3 or 4; c varies between 5 and 20 inclusively; d varies between 1 and 5 inclusively; e varies between 1 and 9 inclusively; and said substrate has a chain > CH- bearing an electroattractive group (or atom). The invention is applicable to organic synthesis.
