我们已经证明，结合使用烯炔复分解和相应的炔基钌卡宾的向金属[1，3]-位移是一个强大的合成工具，以构建寡烯炔。在该反应中，由初始闭环复分解反应（RCM）形成的炔基卡宾中间体经历重复的[1，3]-位移和RCM以得到最终产物。线性聚-1，3-二炔含有重复官能团的类型-[XCH 2CCCCCH 2]n-产生长链共轭低聚烯炔高达ton= 5。
We have demonstrated that the combined use of enyne metathesis and metallotropic [1,3]-shift of the corresponding alkynyl ruthenium carbenes is a powerful synthetic tool to construct oligoenynes. In this reaction, alkynyl carbene intermediates formed from an initial ring-closing metathesis reaction (RCM) undergo repetitive [1,3]-shifts and RCMs to give the final products. Linear poly-1,3-diynes containing repeating functionality of the type −[XCH2CCCCCH2]n− generated long-chain conjugated oligoenynes up ton= 5.
