摘要
The cyclic and linear selectivities of the isomerization of 1,5-hexadiene catalyzed by a substituted titanocene hydride largely depend upon the characteristics of the substituents. Substituents such as methoxyethyl and vinyl favour the formation of cyclic products, whereas allyl and 3-butenyl exhibit high linear selectivities towards the isomerization of 1,5-hexadiene. Factors affecting the reaction process are discussed and the chelation of some substituents on the Cp rings to titanium is proposed. © 1990.
