The reaction of LH [L = {(ArNH)(ArN)–C=N–C=(NAr)(NHAr)};
Ar =2,6-Et2-C6H3] with a commercially
available alane amine adduct (H3Al·NMe2Et) in toluene resulted in the formation of a conjugated bis-guanidinate
(CBG)-supported aluminum dihydride complex, i.e., LAlH2 (1), in good yield. The new complex has been thoroughly
characterized by multinuclear magnetic resonance, IR, mass, and elemental
analyses, including single-crystal structural studies. Further, we
have demonstrated the aluminum-catalyzed hydroboration of a variety
of nitriles and alkynes. Moreover, aluminum-catalyzed hydroboration
is expanded to more challenging substrates such as alkene, pyridine,
imine, carbodiimide, and isocyanides. More importantly, we have shown
that the aluminum dihydride catalyzed both intra- and intermolecular
chemoselective hydroboration of nitriles and alkynes over other reducible
functionalities for the first time.
