通过适当的 THF 络合物与 (1,1'-二茂铁二基) 苯基膦反应，制备了带有应变磷桥联 [1] 二茂铁的锰和钨络合物 (1)。由此获得的单体配合物 [Mn(η5-C5H4R)(CO)2(1)] (R = Me, H) 和 [W(CO)5(1)] 在 THF 或乙腈中用紫外可见光照射 10 分钟后发生开环聚合 (ROP)。因为它们以与游离配体1相同的方式聚合，并且金属片段完整，所以光聚合反应被认为适用于以1作为配体的各种有机金属片段。
Manganese and tungsten complexes bearing a strained phosphorus-bridged [1]ferrocenophane were prepared by reaction of their appropriate THF complexes with (1,1‘-ferrocenediyl)phenylphosphine (1). The monomer complexes [Mn(η5-C5H4R)(CO)2(1)] (R = Me, H) and [W(CO)5(1)] thus obtained were found to undergo a ring-opening polymerization (ROP) upon irradiation with UV−vis light for 10 min in THF or acetonitrile. Because they polymerize in the same manner as the free ligand 1, with the metallic fragment intact, the photopolymerization reaction is considered applicable to a variety of organometallic fragments bearing 1 as a ligand.
