Mo, and W) in a mixture of benzene and THF at room temperature afforded compounds of the type CpFe(CO)2(μ-SPh)M(CO)5 (1) [M = Cr (1a), Mo (1b), and W (1c)] in high yield. However, migration of the thiolato ligand occurred during reactions between CpM(CO)xSPh (M = Fe, x = 2; M = Mo and W, x = 3) and Fe2(CO)9 forming compounds [Fe(μ-SPh)(CO)3]2 and [CpM(CO)x]2 (M = Fe, x = 2; M = Mo and W, x = 3). Single-crystal
CpFe(CO)2SPh 和 M(CO)5THF(M = Cr、Mo 和 W)在苯和 THF 的混合物中在室温下反应得到 CpFe(CO)2(μ-SPh)M( CO)5 (1) [M = Cr (1a)、Mo (1b) 和 W (1c)] 的高产率。然而,硫醇基配体的迁移发生在 CpM(CO)xSPh (M = Fe, x = 2; M = Mo 和 W, x = 3) 和 Fe2(CO)9 形成化合物 [Fe(μ-SPh) (CO)3]2 和 [CpM(CO)x]2(M = Fe,x = 2;M = Mo 和 W,x = 3)。单晶 X 射线衍射分析表明,1c 是一种没有金属-金属键的单硫醇桥联异双金属化合物。未观察到在热或光解条件下通过脱羰在化合物 1 中形成金属-金属键。化合物 1 和 PPh3 之间的反应通过 1 中的 M-S 键裂解产生 CpFe(CO)2SPh 和 PPh3M(CO)5(M
