A β-diketiminato magnesium acetylide and formation of an imido aluminium magnesium hydride compound
摘要:
The reaction of LiC CMe with [((Dip)nacnac)MgI(OEt2)] ((Dip)nacnac = [(DipNCMe)(2)CH], Dip = 2,6-diisopropylphenyl) afforded [{((Dip)nacnac)MgC CMe}(2)] 1 in good yield. Treatment of 1 with AlH3 center dot NMe3 in toluene under reflux afforded a low yield of the novel imido aluminium magnesium hydride compound [{(AlH)(AlH2)(3)(NDip)(3)}(2)Mg] 2. The latter compound features a central Mg2+ ion that is coordinated via hydride ligands to two monoanionic [(AlH)(AlH2)(3)(NDip)(3)](-) fragments. The compounds have been characterised by H-1 and C-13 NMR spectroscopy, IR spectroscopy and the crystal structures of 1 and 2 center dot 4C(7)H(8) have been determined. (C) 2011 Elsevier B.V.
