Abstract

Abstract The titanocene dithiolenato chelates Cp′2Ti(S2C6H3CH3-4) and CpCp′Ti(S2C6H3CH3-4) (Cp = η5-C5H5, Cp′ = η5-C5H4CH3) were prepared by reaction o f Cp′2TiCl2 or CpCp′TiCl2 with equiva­lent amounts of 1,2 -(LiS)2C6H3CH3-4. The structure and the conform ational mobility of the η5-bonded and of the chelating ligands of the dithiolenato complexes are discussed on the basis of their temperature-dependent 1H NMR spectra. The mass spectra show metastable transitions for the fragmentation processes.
