[M(CO)4Lx] {M = Cr， W, L = MeCN,x= 2；M = Mo, L = 2,5‐降冰片二烯（nbd），x= 1}与cyclo‐（P5Ph5）发生了不寻常的转化反应，包括在6族金属羰基上氧化添加P-P键，将MeCN插入P-P键，以及形成M - M键。采用IR、31p {1H} NMR、ESI质谱、单晶X射线晶体学对产物进行了表征。该配合物包含一个金属-金属单元，由新配体的两个末端磷酸基团桥接，（PPh‐PPh‐PPh‐PPh‐PPh‐CMe=N‐PPh）2 -。31p {1H}核磁共振谱显示ABCDE自旋体系与固体中观察到的分子结构一致。此外，还对配合物的热性能进行了评价。
The reaction of [M(CO)4Lx] {M = Cr, W, L = MeCN,x= 2; M = Mo, L = 2,5‐norbornadiene (nbd),x= 1} withcyclo‐(P5Ph5) led to an unusual transformation reaction including the oxidative addition of a P–P bond to the Group 6 metal carbonyl, the insertion of MeCN into a P–P bond, and the formation of an M–M bond. The products were characterized by IR and31P{1H} NMR spectroscopy, ESI mass spectrometry and single crystal X‐ray crystallography. The complexes contain a metal–metal unit bridged by two terminal phosphanido groups of the novel ligand, (PPh‐PPh‐PPh‐PPh‐CMe=N‐PPh)2–. The31P{1H} NMR spectrum shows an ABCDE spin system consistent with the molecular structure observed in the solid state. Furthermore, the thermal properties of the complexes were evaluated.
