Synthesis, properties, and chemoselective reactions of an AlH-BH functional group.

ABSTRACT: A new alumaborane compound containing a {AlH-BH} functional group has been prepared by reaction of the aluminium(I) complex [{(ArCMeN)₂CH}Al] (Ar = 2,6-i-Pr₂C₆H₃) with a boron dihydride species supported by an anionic chelating κ²-N,N ligand. Spectroscopic analysis of the product suggests that it exists as a mixture of isomers in solution with the ligand on boron coordinating in both a κ¹ and κ ² fashion. The dialumane analogue, containing a {AlH-AlH} functional group, was also prepared. Comparison of the structure and bonding of these species by DFT calculations suggests that reactivity of the AlH-BH moiety should be governed by the nucleophilicity of the Al-H and Al-B bonds along with the Le
