Abstract
The present invention relates to a method for preparing acetate compounds using ketene.
Claims17
A method for preparing acetate compounds of the formula (I),
- comprising the steps of
- a) providing at least one compound of the formula (II)
- b) reacting the compound of the formula (II) with a ketene of the formula (III)
- to obtain compounds of the formula (I),
- where R1 is a heteroatom-free C5-C12-hydrocarbon radical, with the proviso that the compounds 1-acetoxymethyl-1,2,2,6-tetramethylcyclohexane and compounds of the formula (A)
- where is a single or double bond, are excluded, wherein the compound of the general formula (II) is subjected to a reaction with a ketene (III) in the absence of an added catalyst.
