  • Hydrogenated short and medium chain oligoalkenes have long been used as components in synthetic lubricants, e.g. Motor oils, used. These are essentially di-, tri- and tetramers which are produced by oligomerization, for example using boron trifluoride as a catalyst and alcohols such as butanol or pentanol as promoters. However, this technology does not specifically lead to higher molecular weight oligomers terminated with vinylidene double bonds.
