The zirconium tert-butylimido complex Zr(NBut)(dpma)(bpy) (9) was available in 43% yield by treatment of Zr(NMe2)2(py)(dpma) with bpy and H2NBut. Transimination on 9 with H2NSiPh3 provided the (triphenylsilyl)imido complex Zr(NSiPh3)(dpma)(bpy) (10) in 34% yield. In an unusual transformation, 10 reacts with excess sodium 2,6-dimethylphenoxide in THF to afford [Na(bpy)][Zr(dpma)(OAr)3] (11), where the
