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