Iron can catalyze head-to-head dimerization of terminal aryl alkynes to give the corresponding (E) selective conjugated enynes in high yields. A variety of substituted aryl acetylenes underwent smooth dimerization using catalytic FeCl(3) and DMEDA in the presence of KO(t)Bu.
铁可以催化末端芳基炔烃的头对头二聚化，以高产率得到相应的（E）选择性共轭烯炔。在 KO(t)Bu 的存在下，使用催化 FeCl(3) 和 DMEDA，各种取代的芳基乙炔能够顺利地进行二聚化。
