The cationic d1-titanocene complexes [{Cp2Ti(L)+2}{BPh-4}] with L = THF (1) and pyridine (2) were very simply prepared by the reaction of [Cp2Ti(Me3SiC≡CSiMe3)] with trimethylammoniumtetraphenylborate via a 1e--oxidation of the 14e--Cp2Ti-unit to the paramagnetic titanium(III) complex under evolution of molecular hydrogen and the alkyne. Complex 2 is the first example of such a cationic-only neutral-ligand containing complexes without anionic ligands that has been characterized by an X-ray structure analysis.
