New Route to Soluble Amidoborane Complexes

New Route to Soluble Amidoborane Complexes

Author: ChemViews

Cameron Jones, Andreas Stasch, and colleagues, Monash University, Melbourne, VIC, Australia, prepared well defined magnesium amidoborane complexes by two new routes: the reactions of ammonia–borane (NH3BH3) with a magnesium(I) dimer [{(DipNacnac)Mg}2], and the reaction of a magnesium(II) iodide complex [(DipNacnac)MgI(OEt2)] with Li(NH2BH3).

They also showed for the first time, that the reaction of ammonia–borane with two magnesium(II) hydride complexes [{(Nacnac)Mg(μ-H)}2] or an alkylmagnesium(II) compound [{(DipNacnac)Mg(μ-nBu)}2] yield well characterized parent amidoborane complexes of magnesium. The crystal structures of all prepared complexes have been obtained and shown to be similar to those previously reported for related compounds.
