BIAN‐Aluminium‐Catalysed Imine Hydrogenation

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 [((Dipp)BIAN)Al(mu-H)(2)Li(OEt2)(2)] was easily prepared from the 2e-reduced BIAN derivative and LiAlH4.
