已经尝试通过使金属三氢化物-路易斯碱加合物[MH 3（quin）]（quin =奎宁环，M = Al、Ga或In）与还原或夺氢试剂反应来制备低氧化态第13族氢化物络合物。第一：1与2，2 ′，6，6 ′-四甲基哌啶氧化物（克里思）反应，得到第一个结构表征的氮氧自由基-第13族氢化物配合物[MH 2（quin）（克里思）]（M = Al或Ga）。与[AlH 3（quin）]的2：1反应得到[AlH（quin）（克里思）2]，其也已在结构上得到验证。讨论了这些反应的机理。
Attempts have been made to prepare low oxidation state group 13 hydride complexes by reacting the metal trihydride–Lewis base adducts, [MH3(quin)] (quin = quinuclidine, M = Al, Ga or In), with reducing or hydrogen abstraction reagents. The 1 : 1 reactions with 2,2′,6,6′-tetramethylpiperidinyl oxide (TEMPO) yield the first structurally characterised nitroxide–group 13 hydride complexes, [MH2(quin)(TEMPO)] (M = Al or Ga). The 2 : 1 reaction with [AlH3(quin)] affords [AlH(quin)(TEMPO)2] which has also been structurally authenticated. The mechanisms of these reactions are discussed.
