The present invention relates to a process of a cis / trans isomerization of an unsaturated compound A being selected from the group consisting of unsaturated ketones, unsaturated ketals, unsaturated aldehydes, unsaturated acetals, unsaturated carboxylic acids, esters of an unsaturated carboxylic acid and amides of an unsaturated carboxylic acid using nitrogen monoxide as cis / trans isomerization catalyst. It has been observed that the isomerization is very efficient and fast.
Description
[0001] This application is a divisional application of Chinese patent application 201380065896.5 (PCT / IB2013 / 061083) with a filing date of December 18, 2013. technical field [0002] The present invention relates to the cis / trans isomerization of unsaturated compounds. [0003] Background of the invention [0004] Unsaturated compounds have carbon-carbon double bonds. These compounds exist in either the cis or trans configuration. In particular, unsaturated compounds with C=O-containing functional groups are technically very important and have different properties, depending on which double bond isomer (cis or trans) is present in the corresponding compound. These compounds are of particular importance for the fields of flavors and fragrances, pharmaceutical compositions and the synthesis of vitamins, especially vitamin K1 and tocopherol. The isomers differ especially with respect to odor and also with regard to their behavior towards asymmetric addition to individual carbo...
