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

Reaction of Ti((N2N)-N-iPr)(NNPh2)(py) with Ph(R)SiH2 (R = H, Ph) or 9-BBN gave reductive cleavage of the N-alpha-Ni-beta bond and formation of new silyl- or boryl-amido ligands. The corresponding reactions of Cp*Ti-{MeC((NPr)-Pr-i)(2)}(NNR2) (R = Me or Ph) with HBPin or 9-BBN gave borylhydrazido-hydride or borylimido products, respectively. N-alpha and N-beta atom transfer and dehydrogenative coupling reactions are also reported.
