Addition-beta-elimination: a new method for the preparation of organometallic compounds

摘要

The addition-beta -elimination mechanism is a powerful method for the production of organometallic derivatives. Using this new method, we report the first transformation of enol ethers into the corresponding vinyl zirconium derivatives. Moreover, the in situ formation of TI(II) and subsequent reaction with halogeno alkynes offers a new route for the preparation of functionalized alkynyl titanium and trismetalated olefin derivatives.
