  Lewis Base Adduct Stabilized Organogallium Azides:  Synthesis and Dynamic NMR Spectroscopic Studies of Novel Precursors to Gallium Nitride and Role of Ammonia as Reactive Carrier Gas

  摘要：

  The organogallium azides (N-3)(2-a)(R)(a)Ga[(CH2)(3)NMe(2)](1-a) (1a-c: R = CH3, (t)Bu; a = 0, 1), (Et)(N-3)(2)Ga (2a), and (Et)(N-3)(2)Ga . L(2b-d: L = thf, H(2)N(t)Bu, py, NC7H13) are quantitatively synthesized by salt metathesis from the chloro species (Cl)(2-a)(R)(a)Ga[(CH2)(3)NMe(2)](1-a) (a = 0, 1) or EtGaCl(2) and sodium azide. The preferential ammonolysis of Ga-N-3 bonds for [Et(2)Ga(N-3)](3) (4) and 1 and 2 is demonstrated; e.g. the dimer Et(2)Ga(mu-NH2)(mu-N-3)GaEt(2) (3) was obtained. The characterization of these compounds by means of elemental analysis, H-1-, C-13-, N-14-, and N-15-NMR, MS, and infrared nu(N-3) data is reported. The dynamics of the intramolecular Ga-N donor-acceptor bonded heterocycle and the azide group is discussed on the basis of variable-temperature NMR data. The barrier of activation of the bimolecular azide exchange process for (N-3)(2)Ga[(CH2)(3)NMe(2)] (1c) amounts about 50 kJ . mol(-1). The role of ammonia as reactive carrier gas for low-pressure metal organic chemical vapor deposition (MOCVD) of GaN with 1c as precursor is discussed.

  monomeric gallium(III) compounds, each containing three different ligands, have been prepared by metathetical and/or ligand redistribution reactions and identified as single compounds in benzene solution and in the solid phase, as appropriate. These compounds include GaRCl(acac) (R = Me, Et, Mes (mesityl, C6H2Me3); acac = 2,4-pentanedionato), GaCl[N(SiMe3)2](acac), and GaMe[N(SiMe3)2](acac). X-ray structural

  通过复分解和/或配体再分布反应已制备了五种单体镓（III）化合物，每种化合物包含三个不同的配体，并视情况在苯溶液和固相中鉴定为单一化合物。这些化合物包括GaRCl（acac）（R = Me，Et，Mes（mesityl，C 6 H 2 Me 3）; acac = 2,4-pentanedionato），GaCl [N（SiMe 3）2 ]（acac）和GaMe [N（SiMe 3）2 ]（acac）。GaMeCl（acac）和GaCl [N（SiMe 3）2的X射线结构研究]（acac）证实了在这些单体分子中存在与镓键合的三种不同的配体。还制备和表征了相关的衍生物GaMeCl（hfac）和GaMesCl（hfac）（hfac = 1,1,1,5,5,5-六氟戊二酮），但这些化合物在室温下缓慢分解。
