Reaction of Ti­(N2iPrN)­(NNPh2)­(py) with Ph­(R)­SiH2 (R = H, Ph) or 9-BBN gave reductive cleavage of the Nα–Nβ bond and formation of new silyl- or boryl-amido ligands. The corresponding reactions of Cp*Ti­{MeC­(NiPr)2}­(NNR2) (R = Me or Ph) with HBPin or 9-BBN gave borylhydrazido-hydride or borylimido products, respectively. Nα and Nβ atom transfer and dehydrogenative coupling reactions are also reported.
