Abstract
Abstract The thermal decomposition of dicyclopentadienyltitanium(IV) dibenzyl in the solid state and hydrocarbon solvents has been investigated. The compound decomposes via intermolecular abstraction of hydrogen atoms from the cyclopentadienyl rings with quantitative formation of toluene. The reaction was found to be of first-order with an activation energy of about 16 kcal mol−1. Deuteration of the benzyl groups leads to a higher activation energy (19 kcal mol−1), whereas deuteration of the Cp ligands does not. A reaction mechanism is proposed in which the rate-determining step is the conversion of one of the σ-bonded benzyl ligands into a π-allylic state.
