application： 10-Undecen-1-ol is used as a flavoring agent. It reacts with tosylated beta-cyclodextrin to prepare beta-cyclodextrin undecenylether. It is used in the synthesis of 10-Undecenylacrylat by reacting with acryloyl and triethylamine. It reacts with carbon monoxide in the presence of dicobalt octacarbonyl and pyridine as a base at pressures greater than 150 bar and temperatures in the range of 100 to 2000C to linear and branched polyesters having relatively high molecular weights (Mn> 10,000 g / mol) in good yields.
