Chemoselective deprotonation of {Cp*Zr(NHtBu)-[N( iPr)C(Me)N(iPr)]}[B(C6F5) 4] (2a) cleanly provides either the neutral enolamide, Cp*Zr(NHtBu)[N(iPr)C(CH2)N( iPr)] (5), or the terminal imido, Cp*Zr(NtBu) [N(iPr)C(CH3)N(iPr)] (6). These two tautomers do not interconvert, and no evidence was obtained for deprotonation of 2a in the presence of an excess of the primary amine tBuNH2.
