The reactions of [ η 5 ‐Cp 2 ZrCl 2 ] (Cp = η 5 ‐C 5 H 5 ) with [K(THF) n ][N(PPh 2 ) 2 ] (n = 1.25—1.5) and K[CH(PPh 2 NSiMe 3 ) 2 ] are reported. The first reaction led to the monoamido complex [ η 5 ‐Cp 2 Zr(Cl)N(PPh 2 ) 2 ] in which the {(Ph 2 P) 2 N} — ligand — via a phosphorous and the nitrogen atom — is coordinated to the zirconium atom in a chelating (η 2 ) fashion. Reaction of the potassium methanide compound, K{CH(PPh 2 NSiMe 3 ) 2 } with zirconocene dichloride yield the carbene‐like mono cyclopentadienyl complex [ η 5 ‐CpZr(Cl){C(PPh 2 NSiMe 3 ) 2 }]. The complex is formed by a salt metathesis and concomitant a cyclopentadiene extrusion.
