Abstract
Abstract Higher olefins are prepared by an exchange reaction between lower olefins and higher organic iodides according to equation I: in the presence of a noble metal catalyst. For example, octene, cyclohexene and decene are produced by an exchange reaction between the corresponding iodides and ethylene in the presence of platinum on various supports, chloroplatinic acid, tris(triphenylphosphine)platinum or bis(triphenylphosphine)ruthenium tricarbonyl.
