Treatment of trans-3,4-diethylzirconacyclopentane complex, which was a selective butene-butene coupling product on zirconium, with methanol followed by bromine gave selectively monobromination product, 2-ethyl-3-methyl-1-bromopentane, in 89% yield with high stereoselectivity. Similarly, non-conjugated diene cyclization products on zirconium were also selectively converted into monohalogenated compounds. These selective monohalogenations proceeded via alkylalkoxyzirconocene complexes. |
