An aluminum(III) monohydride [(2, 6‐ i Pr 2 C 6 H 3 )NC(Me)] 2 AlH(NMe 3 ) ( 1 ) was synthesized by oxidative addition of 1, 2‐diimine (L) {L = [(2, 6‐ i Pr 2 C 6 H 3 )NC(Me)] 2 } with equivalent amounts of H 3 Al · NMe 3 . A lithium salt (LLi 2 ) was obtained when L was treated with elemental lithium. Under these conditions 1, 2‐diimine is reduced to LLi 2 with simultaneous formation of a C=C bond. The LLi 2 is formed in‐situ and treated with AlBr 3 to result in the formation of aluminum(III) monobromide [(2, 6‐ i Pr 2 C 6 H 3 )NC(Me)] 2 AlBr(OEt 2 ) ( 2 ). The two products 1 and 2 show a saturated as well as an unsaturated backbone of the ligand.
