合成了五种新型中性金属配合物，它们都含有9-蒽基阴离子，它们的表征是用有机金属碱处理蒽酮来诱导芳构化。其中三个配合物[(给体)·M(OC14H9)]2(2-4)是二聚体，分别含有钠、锂和钾。2和3的给体是N，N，N‘，N’-四甲基乙二胺(TMEDA)，而4的给体是N，N，N‘，N’，N‘’-五甲基二亚乙三胺(PMDETA)。当使用双金属试剂，如[(TMEDA)·Na(μ-tBu)(μ-tMP)锌(TBu)]时，只分离出含有碱金属的物种(例如，在这种情况下为2种)。相反，配合物5[(TMEDA)·mg(OC14H9)NBU]和6[(TMEDA)·Zn(OC14H9)Et]是单体。在所需的给体溶剂存在下，用一种摩尔当量的正丁基钠、正丁基锂或(三甲基硅基)甲基钾与蒽酮反应，得到了碱金属络合物。在TMEDA存在下，等摩尔数的二正丁基镁和二乙基锌分别在5和6中与蒽酮反应。用X射线结晶学和核磁共振波谱分别测定了2-6的固态结构和芳烃溶液结构。
Five novel neutral homometallic complexes which contain the anthracen-9-olate anion have been prepared and characterised by treating anthrone with an organometallic base to induce aromatisation. Three of these complexes [(donor)·M(OC14H9)]2 (2–4) are dimeric and contain sodium, lithium and potassium respectively. For 2 and 3 the donor is N,N,N′,N′-tetramethylethylenediamine (TMEDA) whilst for 4 it is N,N,N′,N′′,N′′-pentamethyldiethylenetriamine (PMDETA). When bimetallic reagents such as [(TMEDA)·Na(μ-tBu)(μ-TMP)Zn(tBu)] are employed, only the alkali-metal-containing species is isolated (e.g., 2 in this case). Providing a contrast, complexes 5 [(TMEDA)·Mg(OC14H9)nBu] and 6 [(TMEDA)·Zn(OC14H9)Et] are monomeric. The alkali metal complexes were prepared by reacting anthrone with one molar equivalent of either n-butylsodium, n-butyllithium or (trimethylsilyl)methylpotassium in the presence of the required donor solvent. For 5 and 6, equimolar quantities of di-n-butylmagnesium and diethylzinc, respectively, were reacted with anthrone in the presence of TMEDA. The solid-state structures and the arene solution structures of 2–6 have been determined by X-ray crystallography and NMR spectroscopy respectively.
