Several new synthetic routes to the known and new magnesium amidoborane complexes, [{(Nacnac)Mg(NH 2 BH 3 )} 2 ] and [(Nacnac)Mg(NH 2 BH 3 )(THF)] (Nacnac = Dip Nacnac, [{N(Dip)C(Me)} 2 CH] – , or t Bu Nacnac, [{N(Dip)C( t Bu)} 2 CH] – ; Dip = C 6 H 3 i Pr 2 ‐2,6), are reported. These include the reductive dehydrogenation reaction of NH 3 BH 3 (AB) with the magnesium(I) dimer, [{( Dip Nacnac)Mg} 2 ], and the salt elimination reaction of [( Dip Nacnac)MgI(OEt 2 )] with Li(NH 2 BH 3 ). Moreover, the reaction of ammonia–borane with two magnesium(II) hydride complexes, [{(Nacnac)Mg(μ‐H)} 2 ], or an alkylmagnesium(II) complex [{( Dip Nacnac)Mg(μ‐ n Bu)} 2 ], have been shown to yield well defined parent amidoborane complexes of magnesium for the first time. The crystal structures of all prepared complexes were obtained and shown to be similar to those previously reported for related compounds.
