Reactions of Titanium Hydrazides with Silanes and Boranes: N–N Bond Cleavage and N Atom Functionalization

Reaction of Ti­(N₂^iPrN)­(NNPh₂)­(py) with Ph­(R)­SiH₂ (R = H, Ph) or 9-BBN gave reductive cleavage of the N_α–N_β 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. N_α and N_β atom transfer and dehydrogenative coupling reactions are also reported.
