  Synthesis and Characterization of Coronanes:  Multicyclopropane-Fused Macrocyclic Arrays

  摘要：

  Stepwise macrocyclization of the all syn-trans-1,15-quinquecyclopropanedimethanol (4) with iso- and terephthaloyl chlorides and 4,4'-methanediyl-dibenzoic acid (28) gave the corresponding coronanes 22, 23, and 32. The same protocol was used with all syn-trans-1,21-septecyclopropanedimethanol (5) and 2,3-naphthalenedicarboxylic acid to obtain the macrolide 27. Direct macrocyclization of diol 4 and 1,10-phenanthroline-2,9-dicarbonyl chloride (33) and 2,2'-bipyridine-4,4'-dicarbonyl chloride (35) gave the coronanes 34 and 36, respectively. Ring closing metathesis (RCM) of the diene 42 using Cl-2(Cy3P)(2)Ru=CHPh (48) (Grubbs's catalyst) gave the macrocyclic lactone 45. The structures of coronanes 22, 23, 32, 34, 36, and 45 were confirmed by X-ray crystallographic studies which showed the cyclopropyl chain to adopt very differing conformations throughout the series. Several of the macrocycles have significant free pathways through their ring centers, and in the case of compound 34 there is a water molecule hydrogen bonded within the ring. This latter compound has the potential to act as a chiral ligand to metal centers.

  We have successfully synthesized rhodium-containing MOFs with 1:1 abundance ratios of paddle-wheel units of Rh2 and Cu2/Zn2, i.e., [Rh2M2(1,4-bdc)4]·nSolvent (M = Cu: RhCu-DMF, RhCu-EtOH; M = Zn: RhZn-DMF; 1,4-bdc: 1,4-benzenedicarboxylate) by a novel synthetic method involving assembly of discrete paddle-wheel dirhodium(II) tetra(1,4-benzenedicarboxylate) with Cu2+ or Zn2+ ions. The diffraction patterns of these complexes were very similar to the predicted and experimental XRPD patterns reported for [Cu2(1,4-bdc)2]. This result indicates that this method enables the incorporation of coordinatively unsaturated noble-metal sites for the many reported MOFs with multi-carboxy ligands and paddle-wheel nodes.

  我们成功合成了Rh2和Cu2/Zn2的叶轮单元丰度比为1:1的含铑MOF，即[Rh2M2(1,4-bdc)4]·nSolvent (M = Cu: RhCu-DMF, RhCu-EtOH；M = Zn：RhZn-DMF；1,4-bdc：1,4-苯二甲酸），采用离散桨轮二铑（II）四（1,4-苯二甲酸）与 Cu2+ 组装的新型合成方法或 Zn2+ 离子。这些配合物的衍射图与​​ [Cu2(1,4-bdc)2] 报道的预测和实验 XRPD 图非常相似。这一结果表明，该方法能够为许多报道的具有多羧基配体和桨轮节点的 MOF 掺入配位不饱和贵金属位点。
