Probing M−O Bond Cleavage in Silicon and Titanium Bisenolate Radical Cations

Autor: Rolf Söllner, Helmut Werner, Michael Schmittel, Matthias Laubender, Armin Burghart

Publikováno v: The Journal of Organic Chemistry. 64:3077-3085

In this study, several novel sterically congested silicon and titanium bisenolates of exceptional hydrolytic stability have been synthesized and characterized. The structure of the titanium bisenolate T2 could be determined by X-ray structure analysi

Zirconium enolate radical cations in solution—characterisation and kinetics of their mesolytic Zr–O bond cleavage †

Autor: Michael Schmittel, Rolf Söllner

Publikováno v: Journal of the Chemical Society, Perkin Transactions 2. :515-520

Six zirconocene enolate radical cations and one hydroquinone biszirconocene radical cation have been generated and characterised in solution by standard and fast scan cyclic voltammetry. The electroanalytical results along with those from product ana

Electroactive Protecting Groups and Reaction Units, 6. – Titanium Enolate Radical Cations in Solution: Generation, Characterization, and Their Reactions

Autor: Michael Schmittel, Rolf Söllner

Publikováno v: Chemische Berichte. 130:771-777

For the first time titanium enolate radical cations were characterized in cyclic voltammetry experiments. Preparative one-electron oxidation of titanium enolates 1-3 led to the formation of benzofurans B1-B3 through mesolytic Ti-O bond fragmentation

Sterically Shielded Titanocene Enolates – Synthesis, Structure and Their Exceptional Stability towards Hydrolysis

Autor: Michael Schmittel, Rolf Söllner, Helmut Werner, Olaf Gevert

Publikováno v: Chemische Berichte. 130:195-199

The reaction of various sterically congested sodium enolates, generated by quantitative deprotonation of stable enols (of diphenylacetaldehyde in the case of 5), with dichlorotitanocene afforded a series of novel titanium enolates 1-5. The crystal st
