Metallocene compounds, processes for the preparation thereof, catalyst components for olefin polymerization, and processes for the production of olefin polymers
when 4-methyl-5-ethenylthiazole is used as arylalkene the starting material is converted to a pyrrole analogous of thianthrene. On the contrary, when 1,1-diphenylethylene is used, the main product observed is benzophenone. Nitrones are obtained only as minor products. An unusual coupling product, where a substitution reaction has occurred on the carbon bearing the nitro group, is also obtained. trans-Stilbene
