Nondissociative mechanism for decomposition of dialkylzirconocenes to produce alkene–zirconocene–phosphine complexes
Abstract
Examination of the reaction of [Cp2Zr(n-octyl)2](2) with D2CCH–n-hexyl or styrene in the presence of PMe3 by NMR spectroscopy rules out dissociative mechanisms for the conversion of (2) into alkene–ZrCp2–PMe3 complexes involving free ZrCp2 and supports non-dissociative mechanisms (Cp = cyclopentadienyl).
