The aluminum amides R2AlN(Ar)SiMe3 [R = Et, Ar = Dipp, 1 (Dipp = 2,6-iPr2C6H3-); R = iBu, Ar = Dipp, 2; R = Et, Ar = Mes, 3 (Mes = 2,4,6-Me3C6H 2-); R = iBu, Ar = Mes, 4] were prepared by ethane or hydrogen elimination reaction between Et3Al or iBu2AlH and ArN(H)SiMe3 in refluxing hexane solution. The LiCl salt elimination route resulted in the formation of the monomeric aluminum amide Et 2AlN(Mes)SiPh3 (5) featuring three-coordinate aluminum and nitrogen centers. In addition, the synthesis and characterization of the dinuclear species Ph2Si{N(Mes)AlEt2}2 (6) and the hydride-bridged eight-membered ring compound {MesN(SiMe3)Al(iBu) (μ-H)}2(μ-LiH)(μ-iBu2AlH) (7) are reported. All compounds have been characterized by 1H and 13C{ 1H} NMR spectroscopy, and compounds 5, 6, and 7 have also been characterized by single-crystal X-ray crystallography.
