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

Dehydrocoupling reactions between the boranes HBpin and 9‐borabicyclo[3.3.1]nonane and a range of amines and anilines ensue under very mild reaction conditions in the presence of a simple β‐diketiminato magnesium n‐butyl precatalyst. The facility of the reactions is suggested to be a function of the Lewis acidity of the borane substrate, and is dictated by resultant pre‐equilibria between, and the

The reaction of a β-diketiminate-stabilized calcium diphenylamide with the dialkylborane 9-BBN allows the synthesis of a β-diketiminate-stabilized calcium borohydride along with an amidoborane reaction coproduct via a likely σ-bond metathesis mechanism.
