Abstract
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.
