Synthesis of Magnesium Compounds XMgY(X=R,Br; Y= NR2, NPh2) and Studies of CO2 insertion into Mg-C and Mg-N

The 1:1 reaction between MgR2 and diphenylamine gave heteroleptic alkyl
-magnesium amide monomeric compounds [RMgNPh2(THF)2] [R=Et (1) and iPr (2)]. Subsequently, addition of stronger donor solvent HMPA to compound 1 results in the disproportionation reaction to give a bisamidomagnesium crystal [Mg(NPh2)2(HMPA)2] (3). The different size secondary amine HNEt2 or HN(SiMe3)2 reacting with Grignard reagent EtMgBr produced diethylamino-bridging and bromo-bridging Hauser base [(Me3Si)2NMg(£g-Br)(OEt2)]2 (4) and [BrMg(£g-NEt2)(HMPA)]2(5) respectively. Unexpectedly, [(Me3Si)NMg
(£g-OEt)(THF)]2 (6) was obtained from the reaction of MgEt2 and HN(SiMe3)2 in the refluxing THF solution. Additionally, iPrMgBr and MgY2 (Y = iPr, C
