  • Patent number: 9765002
    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 polythiol as cis/trans isomerization catalyst. It has been observed that the isomerization is very efficient and fast.
