From vinyl sulfides, sulfoxides and sulfones to vinyl zirconocene derivatives

An easy and straightforward new method for the preparation of sp 2 zirconocene derivatives from a wide range of heterosubstituted alkenes such as vinyl sulfides, sulfoxides and sulfones is described. In all cases, a complete isomerization of the stereochemistry is observed and only the E-isomer is obtained. The reactivity of the resulting vinylic organometallic can be increased by a transmetalation reaction into organocopper, organozinc or organopalladium species and, therefore, several carbon-carbon formation were easily realized.

From vinyl sulfides, sulfoxides, and sulfones to vinyl transition metal complexes

A transformation with promising versatility: The vinyl zirconium complex 1 can be prepared readily in situ from the educts mentioned in the title and reacts with electrophiles, including other transition metal complexes, to give polysubstituted olefins (s
