Racemic and/or optically active 7-methyltropone-Fe(CO)3, tropone-Cr(CO)3, and endo- and exo-homotropone-Fe(CO)3 reacted with 8-oxoheptafulvene to afford the corresponding racemic and/or optically active heptafulvalene metal complexes, respectively. Endo- and exo-homoheptafulvalene-Fe(CO)3 reacted with TCNE to give [2+4]π and [2+8]π cycloadducts, respectively.
外消旋和/或旋光性 7-甲基托酮-Fe(CO)3、托酮-Cr(CO)3 和内-和外-同托酮-Fe(CO)3 与 8-氧代七富烯反应得到相应的外消旋和/或分别具有光学活性的七富瓦烯
金属配合物。内-和-外-高七富瓦烯-Fe(CO)3 与TCNE 反应,分别得到[2+4]π 和[2+8]π 环加合物。
