Abstract
The present invention relates to a method for preparing a compound of the formula (I) with a specific definition of the substituent R3 a mixture and also a corresponding application/use.
Claims13
A method for preparing a compound of the formula (I)
- where R3 is selected from H and straight-chain, branched or cyclic C1-12-alkyl groups, the method comprising:
- providing or preparing a compound of the formula (II)
- where R3 has the definition selected for formula (I) and
- carrying out platinum-catalysed oxidation of the compound of the formula (II) with gaseous oxygen to give the compound of the formula (I).

A process comprising carrying out Heyns oxidation (a) for oxidizing a compound of the formula (II)
- where R3 is selected from H and straight-chain, branched or cyclic C1-12-alkyl groups,
- wherein the Heyns oxidation is carried out without addition of base or buffer.
A mixture comprising
- a catalyst comprising platinum as a solid, optionally comprising platinum as a solid on a support material, further optionally comprising platinum as a solid on carbon,
- and also
- one or more compounds selected from the group consisting of
- (a) compounds of the formula (II)
- where R3 is selected from H and straight-chain, branched or cyclic C1-12-alkyl groups,
- and optionally one or more compounds selected from the group consisting of (b) compounds of the formula (III)
- where R3 is selected from H and straight-chain, branched or cyclic C1-12-alkyl groups.
