η-Cycloheptatrienyltitanium chemistry: halogeno-, tertiary phosphine, and alkyl derivatives: crystal structures of [Ti(η-C7H7)(C4H8O)(µ-Cl)]2 and Ti(η-C7H7)(Me2PCH2CH2PMe2)Et

Abstract

The new binuclear compounds [Ti(η-C₇H₇)(C₄H₈O)(µ-Cl)]₂ reacts with bis-1,2-(dimethylphosphino)ethane giving [Ti(η-C₇H₇)(Me₂PCH₂CH₂PMe₂)Cl] from which the alkyl derivatives [Ti(η-C₇H₇)(Me₂PCH₂CH₂PMe₂)R](R Me of Et) may be prepared; the crystal structures of [Ti(η-C₇H₇)(C₄H₈O)(µ-Cl)]₂ and [Ti(η-C₇H₇)(Me₂PCH₂CH₂PMe₂)Et] have been determined.
