親核試劑剛在-78℃時與帶官能基雙烯三羰鐵錯合物反應,得到高丙烯三羰鐵陰子錯合物之中間體,加三氟醋酸質子化,分別得到親核試劑加成在中間位置的烯類、五環酮及含鐵的五酮錯合物。
Reaction Functionalized (η^4- diene)Fe(CO)_3 Complexes with Carbon Nucleophiles give (η^1, η^2-but-3-en-1-yl)Fe(CO)_3 anion complexes. The postulated anionic intermediates reacted with trifluoroacetic acid produced alkenes, cyclopentanones and mettallacyclopentanones with nucleophiles at the internal position of the starting complexes.
