  寡核镓氮笼化合物：从氢化肼到氮化镓的分子中间体

  摘要：

  酰肼可潜在地用作通过热解生成GaN的简便起始化合物。然而，分解途径是复杂的，并且在很大程度上取决于与镓原子和肼基相连的取代基。本文介绍了一些系统的研究，以研究肼镓加合物Bu t 3 Ga←NH 2 -NHMe（1a）和二聚酰肼[R 2 Ga（N 2 H 2 R'）] 2（2b，R = Bu t，R'= Bu t；2c，R = Pr i，R'= Ph; 2d，R = Me，R'= Bu t），它们的分子核中具有四元或五元杂环。加热所述加合物的1A至170℃，得到的杂环化合物卜吨2镓（μ-NH 2）[μ-N（Me）的-N（= CH 2）]加布吨2（3），通过N-N裂解键和重新排列。3进一步转化在400℃到四聚体镓氰化物（卜吨2 GaCN）4（4）。酰肼（Bu t 2 Ga）2（NH-NHBu t）2（2b的热解）在270和420之间的温度下℃下导致的所有N-N键的断裂和形成的octanucle

  Adducts of organogallium chlorides with hydrazines and the formation of dimeric dialkylgallium hydrazides possessing different ring sizes

  摘要：

  The dialkylgallium chlorides R2GaCl (R = Me, Et, CMe3) reacted with hydrazines H2N-N(H)R' (R' = CMe3, C6H5) to form the adducts R2ClGa <- NH2-N(H)R' (1-4), in which the gallium atoms are coordinated by the NH2 nitrogen atoms of the hydrazine ligands. Treatment of these adducts with tert-butyllithium as a base afforded dialkylgallium hydrazides (R2Ga-N2H2R')(2) [5(R = R' = CMe3) and 6 (R = CMe3, R' = C6H5)] by deprotonation of the hydrazine ligands and precipitation of LiCl in two cases only. The remaining adducts gave a substitution reaction at gallium or an unclear reaction course. The hydrazides 5 and 6 adopt different structures in the solid state. The tri(tert-butyl) compound 5 possesses a four-membered Ga2N2 heterocycle in its molecular core with two exocyclic N-N bonds, which represents the structural motif usually observed for dialkylgallium hydrazides. 6 has a five-membered Ga2N3 heterocycle with one endocyclic and one exocyclic N-N bond. That structure is preserved in solution as clearly shown by NMR spectroscopy. The behaviour of 5 in solution is more complicated, which may be caused by cis/trans isomerization.
