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 89percent 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.
