Synthesis and reactivities of titanocene-oxo complexes and rhodium-catalyzed oxidative amidation
… on oxo synthesis established that starting from titanocene ethylene complexes, pyridine N-oxide was an effective oxidant to generate Cp*2Ti=O(L) in high yield while styrene oxide was the oxidant of choice for Cp’2Ti=O(L). These complexes were then demonstrated to readily undergo cycloaddition …

Azobenzene, Diphenylacetylene and Aromatic Nitrogen Heterocycles Coordinated to Early Transition Metal Metallocenes
The structures of titanocene(azobenzene) (I), vanadocene(azobenzene) (II), vanadocene(diphenylacetylene) (III) and molybdenocene(diphenylacetylene) (IV) were determined using X-ray crystallography.

Bildung und Nutzung multinuklearer Titanocenkomplexe mit N-heterocyclischen Brückenliganden
Within the scope of this theses reactions of titanocene sources and higher anellated aromatic N-heterocycles have been investigated and the properties of resulting products were described from different points of view. Quinoxalines and quinolines have been shown to undergo dehydrogenative C-C …

The characterization and chemistry of {\it mono\/}- and {\it bis\/}-cyclopentadienyl titanium thiolates.
… affording relatively insoluble titanocene dithiolate derivatives 2.1 and 2.2 respectively. Alternatively, 2.2 can be prepared by the reaction of Cp$\rm\sb2TiPh\sb2$ with dithiol. The spectroscopic and analytical data are consistent with the formulation of 2.1 and 2.2 as the …

Transition-metal catalysis of cyclocarbonylation and cycloisomerization reactions
… enyne cycloisomerization is described. Titanocene dicarbonyl was shown to catalyze the cycloisomerization of enynes and dienynes to 1,4-dienes and allylic allenes, respectively. Examination of the scope of the reaction demonstrates that only trans-substituted enynes were cyclized. The …
