A new synthetic itinerary to silole from Si-tethered diynes is reported. In this protocol, the Si-tethered diyne manifests definitely the reactivity of monoyne to form the lithio silole via zirconacyclopetadiene, 1,4-diiodo-1,3-butadiene and the corresponding dilithiodiene successively. Lithio siloles thus obtained above could be easily functionalized to give various types of silole derivatives. Complex structure like bridged bis-silole compounds could also be constructed by this process.

 

噻咯 (Silole)在材料化學研究領域非常重要。本文以矽橋連二炔為起始物發展了合成噻咯的新方法。矽橋連二炔以單炔的反應性通過锆雜環戊二烯，相應的1，4-二碘-1，3-丁二烯以及1，4-二锂-1，3-丁二烯這樣的反應過程最終形成了锂代噻咯。锂代噻咯可以被很容易地進一步官能團化，從而形成不同的噻咯衍生物。通過此方法，可以得到用其它方法很難得到的結構複雜的橋連雙噻咯化合物。
