2-dimethylenecyclobutane, a Perfluorinated Diene Ligand — Carbonyl(η5-cyclopentadienyl)(η4-octafluoro-1, 2-dimethylenecyclobutane)manganese The [2+2]-cycloaddition product of tetrafluoroallene (1), octafluoro-1, 2-dimethylenecyclobutane (2) reacts with tricarbonyl(η5-cyclopentadienyl)manganese (4) replacing two carbonyl ligands to give carbonyl(η5-cyclopentadienyl)(η4-octafluoro-1, 2-dimethylenecyclobutane)manganese
Octafluoro-1, 2-dimethyleneecyclobutane, a Perfluorinated Diene Ligand - Carbonyl (η5-cyclopentadienyl) (η4-octafluoro-1, 2-dimethyleneecyclobutane) manganese 四氟丙二烯 (1),八氟-1的[2+2]-环加成产物, 2-二亚甲基环丁烷 (2) 与三羰基 (η5-环戊二烯基) 锰 (4) 反应,取代两个羰基配体,得到羰基 (η5-环戊二烯基) (η4-八氟-1,2-二甲基环丁烷) 锰 (5)。根据5的IR光谱,配体2是强π受体。在 1 的二聚反应的挥发性较低的副产物中,其三聚体的水解产物可以通过 X 射线衍射在结构上表征为螺环化合物十氟-5-亚甲基-螺 [3.3] 庚烷-2-羧酸 (3 )。5的结构也通过X射线晶体结构测定来确定。
