烯烴交叉復(fù)分解反應(yīng)是指兩種端基烯烴在Ru(II)-卡賓(Grubbs Catalyst)催化下，放出乙烯的烯烴復(fù)分解反應(yīng)。從統(tǒng)計(jì)學(xué)來看，反應(yīng)應(yīng)該生成三種可能的幾何異構(gòu)體，再加上每種異構(gòu)體各有 E/Z構(gòu)型，因此共有六種產(chǎn)物。
此反應(yīng)的選擇性近期得到更進(jìn)一步的研究，有各種反應(yīng)實(shí)例表明不同反應(yīng)活性的烯烴都能高產(chǎn)率和高選擇性的反應(yīng)。
烯烴復(fù)分解反應(yīng)，按照反應(yīng)過程中分子骨架的變化，可以分為五種情況：開環(huán)復(fù)分解、開環(huán)復(fù)分解聚合、非環(huán)二烯復(fù)分解聚合、關(guān)環(huán)復(fù)分解以及交叉復(fù)分解反應(yīng)。
在1990年代， Robert H.Grubbs發(fā)現(xiàn)了實(shí)用性非常高的催化劑。之后烯烴復(fù)分解反應(yīng)成為有機(jī)合成化學(xué)里最常用的反應(yīng)之一。
