    N-heterocyclic carbene coordinated gallanes and chlorogallanes
    摘要:
    The preparation of the N-heterocyclic carbene coordinated gallium complexes [GaH3(IXy)] (1), [GaH3(IDipp)] (2), [GaClH2(IMes)] (3) and [GaCl2H(IMes)] (4), where IXy = 1,3-bis(2,6-dimethylphenyl)imidazol-2-ylidene, IDipp = 1,3-bis(2,6-diisopropylphenyl) imidazol-2-ylidene and IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene, are reported. All four complexes have been characterised by H-1, C-13 NMR and IR spectroscopy and, for complexes 2, 3 and 4, single crystal X-ray structure determination. These compounds represent some of the most thermally stable molecular gallium hydrides known, with 4 being the most thermally stable gallium hydride reported (dec. 274 degrees C). These remarkable thermal stabilities translate to significant aerobic stability such that all four compounds may be handled in dry air without significant decomposition. Compounds 2, 3 and 4 exist as distorted tetrahedra in the solid state with gallium to carbene C-donor bonds that shorten with increasing Lewis acidity of the gallium centre. Compound 2 co-crystallizes with 1 equiv. of 2,6-diisopropylphenylaniline and exhibits several weak intermolecular bonding interactions in the solid-state. (C) 2009 Elsevier B.V. All rights reserved.

  • Azido- and amido-substituted gallium hydrides supported by N-heterocyclic carbenes
    作者:Anindya K. Swarnakar、Michael J. Ferguson、Robert McDonald、Eric Rivard
    DOI:10.1039/c6dt04595b
    日期:——
    Despite recent advances in main group N-heterocyclic carbene (NHC) coordination chemistry, gallium hydrides remain, in large part, an unexplored area of research. In this paper we outline efficient routes to azide- and amido-functionalized gallium hydrides such as NHC·GaH2N3 and NHC·GaH2N(SiMe3)2 and explore these species as potential precursors to HGaNH complexes and bulk gallium nitride (GaN).
    尽管在主要的N-杂环卡宾(NHC)配位化学方面取得了最新进展,但氢化镓在很大程度上仍是一个尚未探索的研究领域。在本文中,我们概述了获得叠氮化物和酰胺基官能化的氢化物(例如NHC·GaH 2 N 3和NHC·GaH 2 N(SiMe 3)2)的有效途径,并探讨了这些物质作为HGaNH配合物和块状氮化镓( GaN)。
