Abstract

Reacting o-C₆H₄F(CH = NC₆H₃iPr₂-2,6) (L) with H₃Al·NMe₃ resulted in the aluminum dihydride with coordinated NMe₃ of composition [o-C₆H₄F(CH₂NC₆H₃iPr₂-2,6)]AlH₂(NMe₃)(1). Furthermore, the aluminum monohydride [o-C₆H₄N(C₆H₃iPr₂-2,6)(CH₂NC₆H₃iPr₂-2,6)]AlH(NMe₃) (2) was prepared by treatment of the anilido-imine ligand o-C₆H₄N(C₆H₃iPr₂-2,6)(CH = NC₆H₃iPr₂-2,6) (L∗) with H₃Al·NMe₃ in high yield. The formations of the two complexes both involve aluminum hydride addition to the C=N double bond. Compounds 1 and 2 were characterized by ¹H NMR and IR spectroscopic, elementary analysis, and single-crystal X-ray diffraction studies.
