Abstract

Hydrogenations have been dominated by transition metal catalysis, while the use of more abundant and inexpensive main group metal catalysts has remained a great challenge. Here, a bimetallic Li/Al dihydride was successfully applied to catalytic hydrogenations of imines. The catalyst [(^DippBIAN)Al(μ-H)₂Li(OEt₂)₂] was easily prepared from the 2e-reduced BIAN derivative and LiAlH₄.

Keywords: aluminium; hydrides; hydrogenation; imines; main group metal catalysis.
