Abstract:  The interaction of Cp₂TiH containing catalyst with C₁₀ and C₁₂ cycloal­kadienes yields Ai-cycloalken-l-ylbis(cyclopentadienyl)titanium(III) com­pounds (n= 2—6) but only the stable allyl compounds are characterized by e.s.r. and electronic absorption spectra. All of them cooperate in transforming the substrate by stepwise double bond shifts into the equilibrium mixture of isomers. The conjugated cycloalkadienes constituted minor components in C₁₀ and C₁₂ equilibrium mixtures while in C₈ diene it was the only product.
