A route to new and existing transition metal phosphine complexes is provided by the reaction of coarse-grain metal powders and phosphoranes in diethyl ether, as exemplified here by Nil3(PMe3)2, FeBr3(PPhMe2)2 and Mnl2(PPhMe2).

Unactivated zinc powder reacts with R3Pl2(RMe, Et, Prn, Bun) to yield the unexpected 1 : 1 adducts of zinc(II), Zn(R3P)I2; the X-ray crystal structure of triethylphosphine complex shows it to be dimeric [Zn(PEt3)l2]2.
未活化的锌粉与 R3Pl2(RMe、Et、Prn、Bun)发生反应,生成了意想不到的 1 : 1 的锌(II)加合物 Zn(R3P)I2;三乙基膦配合物的 X 射线晶体结构显示它是二聚体 [Zn(PEt3)l2]2。
The reaction of coarse-grain manganese powder with diiodotrimethylphosphorane to form [Mn(PMe3)I2] n , which reacts with trace quantities of molecular oxygen to form the mixed (+2/+3) oxidation state complex [Mn2(PMe3)3I5]PMe3

Coarse-grain unactivated manganese powder reacts with Me3Pl2 in diethyl ether to form the polymeric [Mn(PMe3)I2]n complex, I, which reacts with trace quantities of dioxygen to form dinuclear [Mn2(PMe3)3I5]·PMe3, II, the first mixed oxidation state (+2/+3) manganese complex which contains phosphine ligands; both I and II react with an excess of dioxygen to form the monomeric [Mn(PMe3)2I3].
