Abstract

Abstract: An aluminum(III) monohydride [(2, 6‐ i Pr2 C6 H3 )NC(Me)]2 AlH(NMe3 ) (1 ) was synthesized by oxidative addition of 1, 2‐diimine (L) {L = [(2, 6‐ i Pr2 C6 H3 )NC(Me)]2 } with equivalent amounts of H3 Al· NMe3 . A lithium salt (LLi2 ) was obtained when L was treated with elemental lithium. Under these conditions 1, 2‐diimine is reduced to LLi2 with simultaneous formation of a C=C bond. The LLi2 is formed in‐situ and treated with AlBr3 to result in the formation of aluminum(III) monobromide [(2, 6‐ i Pr2 C6 H3 )NC(Me)]2 AlBr(OEt2 ) (2 ). The two products1 and2 show a saturated as well as an unsaturated backbone of the ligand. Abstract :
