Patent ID: 6995291

Claim:
A process for the oxidation of an unsaturated alcohol of formula wherein: R 1 represents a hydrogen atom, a C 1 to C 20 linear, branched or cyclic saturated or unsaturated hydrocarbon group, said hydrocarbon group optionally being substituted and also optionally including one or two oxygen or nitrogen atoms; R 2 represents a C 2 to C 20 linear, branched or cyclic alkenyl, alkandienyl or alkantrienyl hydrocarbon group, said hydrocarbon group optionally being substituted and also optionally including one or two oxygen or nitrogen atoms; or said R 1 and R 2 optionally may be bonded together to form an unsaturated ring having 5 to 20 carbon atoms, said ring optionally being substituted and also optionally including one or two oxygen or nitrogen atoms; wherein the optional substituents of R 1 , R 2 and of the ring which said R 1 and R 2 together may optionally form, are C 1 to C 15 linear, branched or cyclic alkyl, alkenyl or aromatic groups; into a corresponding unsaturated aldehyde or ketone of formula wherein R 1 and R 2 are as defined in formula (I); wherein the oxidation is performed by a hypochlorite salt of formula M(OCl) n (III) in which M represents an alkaline metal, in which case n is 1, or an alkaline-earth metal in which case n is 2; and in the presence of a catalytic amount of a N-(2,2,6,6-tetraalkyl-4-piperidinyl-N-oxyl)-2-amino-1,3,5-triazine compound.
