Convenient one-pot synthesis of half-sandwich η-cycloheptatrienyl and η-toluene derivatives of the metals titanium and zirconium; crystal structure of [Zr(η6-C6H5Me)(PMe3)2Cl2]
摘要:
The compounds [M(eta-7-C7H7)L2Cl] (M = Ti; L2 = (PMe3)2, Me2NCH2CH2NMe2, Me2PCH2CH2PMe2. M = Zr; L2 = Me2NCH2CH2NMe2) and the eta-6-arene derivative [Zr(eta-6-C6H5Me)(PMe3)2Cl2] have been prepared in a one-pot reduction of MCl4 in the presence of L2 and an excess of cycloheptatriene or toluene, respectively. The crystal structure of [Zr(eta-6-C6H5Me)(PMe3)2Cl2] has been determined.
