Reaction of the carbonyl anion Fe4(CO)132– with strong acid in the presence of diphenylphosphine affords the trinuclear phosphido bridged cluster (µ-H)2Fe3(CO)8(µ-PPh2)2(1) which has been fully characterized by X-ray diffraction; ready intramolecular elimination of benzene from (1) at room temperature in the presence of CO yields the phosphinidene complex Fe3(CO)9(µ3-PPh)2(2).
在二苯膦的存在下,羰基阴离子Fe 4(CO)13 2–与强酸反应,得到三核磷桥联簇(µ-H)2 Fe 3(CO)8(µ-PPh 2)2(1),通过X射线衍射已充分表征;在室温下,在存在CO的情况下,从(1)分子内消除苯可得到次膦酸酯络合物Fe 3(CO)9(µ 3 -PPh)2(2)。
