Indenyl-(Ind) and fluorenyl-(Fl) substituted NHC-stabilized alanes and gallanes (NHC)·EHR 1-12 (NHC = IiPr, IiPr, IMe; E = Al, Ga; R = Ind, Fl) were prepared reaction of the corresponding NHC-iodoalanes and -gallanes with LiInd and LiFl, respectively. Analogously, the alane adducts with two Ind/Fl substituents (NHC)·AlHR13-18 (NHC = IiPr, IiPr, IMe; R = Ind, Fl) were obtained by using two equivalents of LiInd/LiFl. Elimination of indene and fluorene was induced thermally affording unusual dimeric and trimeric NHC-alane adducts {(NHC)·AlH}-μ-Fl 19-20 and {(NHC)·AlH-μ-R}21-23 (R = Ind, Fl; = 2, 3) with bridging indenyl and fluorenyl ligands.
茚基（Ind）和芴基（Fl）取代的NHC稳定的铝烷和镓烷（NHC）·EHR 1-12（NHC = IiPr、IiPr、IMe；E = Al、Ga；R = Ind、Fl）分别通过相应的NHC-碘代铝烷和-碘代镓烷与LiInd和LiFl反应制备。类似地，通过使用两当量的LiInd/LiFl得到具有两个Ind/Fl取代基的铝烷加合物（NHC）·AlHR13-18（NHC = IiPr、IiPr、IMe；R = Ind、Fl）。茚和芴经热消除后，得到具有桥连茚基和芴基配体的不寻常的二聚体和三聚体NHC-铝烷加合物{（NHC）·AlH}-μ-Fl 19-20和{（NHC）·AlH-μ-R}21-23（R = Ind、Fl； = 2、3）。
