| Abstract: | The reactions of η5‐Cp2ZrCl2] (Cp = η5‐C5H5) with K(THF)n]N(PPh2)2] (n = 1.25—1.5) and KCH(PPh2NSiMe3)2] are reported. The first reaction led to the monoamido complex η5‐Cp2Zr(Cl)N(PPh2)2] in which the {(Ph2P)2N}— ligand — via a phosphorous and the nitrogen atom — is coordinated to the zirconium atom in a chelating (η2) fashion. Reaction of the potassium methanide compound, K{CH(PPh2NSiMe3)2} with zirconocene dichloride yield the carbene‐like mono cyclopentadienyl complex η5‐CpZr(Cl){C(PPh2NSiMe3)2}]. The complex is formed by a salt metathesis and concomitant a cyclopentadiene extrusion. |
