Carbocyclic three-, four- and five-membered rings are formed in good to excellent yield (87–100%) upon treatment of the appropriate α,ω-diiodide with t-butyllithium in pentane-ether solution at −23°C. The corresponding dibromides do not undergo clean cyclization.
在23°C的戊烷醚溶液中,用叔丁基锂处理适当的α,ω-二碘化物时,形成的碳环三元,四元和五元环的收率好至极好(87–100%)。相应的二溴化物不经过干净的环化。
