Rosenthal's Reagent
Rosenthal's reagent is a metallocene bis(trimethylsilyl)acetylene Coordination complex, complex with zirconium (Zirconocene, Cp2Zr) or titanium (Cp2Ti) used as central atom of the metallocene fragment Cp2M. Additional Ligand, ligands such as pyridine or Tetrahydrofuran, THF are commonly used as well. With zirconium as central atom and pyridine as ligand, a dark purple to black solid with a melting point of 125–126 °C is obtained. Synthesizing Rosenthal's reagent of a titanocene source yields golden-yellow crystals of the titanocene bis(trimethylsilyl)acetylene complex with a melting point of 81–82 °C. This reagent enables the generation of the themselves unstable titanocene and zirconocene under mild conditions. The reagent is named after the German chemist (born 1950) and was first synthesized by him and his co-workers in 1995. Synthesis Rosenthal's reagent can be prepared by Redox, reduction of Titanocene dichloride, titanocene or zirconocene dichloride with magnesium ...
