of Fe2(CO)9 (10) with ferrocenenyl dichlorophosphines of different substitution is discussed. Single FcPCl2, (5) as well as 1,1’‐ (6) and 1,2‐ (9) difunctionalized phosphines were used, of which 6 and 9, were prepared in a novel straightforward synthetic process. Substrate 5 gave butterfly‐shaped Fe2(CO)6(μ2‐Cl)(μ2‐PFcCl) and Fe2(CO)6(μ2‐PFcR1)(μ2‐PFcR2) (R1, R2=Cl, H). In addition, nido‐Fe3(CO)10(μ3‐PFc)
讨论了Fe 2(CO)9(10)与不同取代基二茂铁基二氯膦的反应化学。使用单一的FcPCl 2,(5)以及1,1'-(6)和1,2-(9)双官能化的膦,其中6和9是通过新颖,简单的合成方法制备的。基板5,得到蝴蝶形的Fe 2(CO)6(μ 2 -Cl)(μ 2 -PFcCl)和Fe 2(CO)6(μ 2 -PFcR 1)(μ2 -PFcR 2)(R 1,R 2 = Cl,H)。此外,巢-Fe 3(CO)10(μ 3 -PFc)和巢-Fe 3(CO)9(μ 3 -PFc)2得到的。1,1'-功能化6桥接Fe 2(CO)6实体的两端。其中,观察到了两个1,1'-取代基之间迄今为止最小的非结合P⋅⋅⋅P距离(2.7674(12)Å)。此外,一种“有机金属八碳戊烯”得到含有两个[2]二茂铁金属的实体。八元环状结构的二茂铁基轴扭曲了35.31(9)°。的1,2-用法(PCL 2)2官能9产生的P-P
