Disubstituted 1,8‐diamidonaphthalene complexes of B and Al were accessed via hydrogen or methane elimination reactions from readily available borane or trimethylaluminum. Trigonal planar borane complexes, HB[1,8‐(NR)C10H6] (R = iPr, 4 and R = Ph, 5), were observed to be air stable, a feature attributed to B–N pπ–pπ bonding and supported by computations. Bimetallic Al complexes, [Al(CH3)2]2[(RN)2C10H6] (R = iPr
B和Al的双取代1,8-二重氮萘络合物可通过氢或甲烷消除反应从易得的硼烷或三甲基铝中获得。观察到三角形平面硼烷络合物HB [1,8-(NR)C 10 H 6 ](R = i Pr,4和R = Ph,5)具有空气稳定性,这归因于B–N pπ– pπ键合并受计算支持。双金属Al络合物[Al(CH 3)2 ] 2 [(RN)2 C 10 H 6 ](R = i Pr,7,R = Ph,8或R = i Pr / Np,9)是通过单晶X射线衍射分析记录的,并显示了带有桥联二亚氨基萘配体的折叠的四元M 2 N 2环。在R = Ph的情况下,分离出单金属铝络合物MeAl(OEt 2)[1,8-(PhN)2 C 10 H 6 ](6)作为二乙醚加合物。结构数据表明,与已报道的三甲基甲硅烷基类似物相比,二烷基和二芳基是更强的σ键配体。
