Abstract

Acyclic alpha , omega -dienes of the general formula I <IMAGE> in which R is an alkyl radical and A is a divalent aliphatic group which optionally has one or more alkyl substituents and can have one or more isolated olefinic double bonds, are obtained by reacting a cyclic olefine of the general formula II <IMAGE> with a beta -olefine of the general formula III <IMAGE> in which R<1> is an alkyl radical, in the presence of an olefine disproportionation catalyst, to give an intermediate of the formula <IMAGE> which is then further reacted with ethylene in the presence of an olefine disproportionation catalyst, while maintaining a molar ratio of ethylene to intermediate of at least 2:1.
