  Conformational Control of Benzyl-o-carboranylbenzene Derivatives and Molecular Encapsulation of Acetone in the Dynamically Formed Space of 1,3,5-Tris(2-benzyl-o-carboran-1-yl)benzene

  摘要：

  A 1,3,5-substituted benzene platform has been widely used in the fields of supramolecular chemistry and molecular recognition. Here, we show that 1,3,5-tris(2-benzyl-o-carboran-1-yl)benzene 6 exhibits solvent-dependent conformation in the crystalline state. Recrystallization from dichloromethane-n-pentane gave the anti conformation 6-anti, while recrystallization from methanol-acetone gave the syn conformation 6-syn, in which the three benzyl-o-carboranyl moieties are located to one side of the central benzene ring. Interestingly, one acetone molecule is captured in the pi-rich space of 6-syn and two complexes facing each other encapsulate two acetone molecules in a pi-rich container formed by the eight benzene rings. The inclusion involves several weak interactions, that is, T-shaped C-H center dot center dot center dot pi interactions, and C-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions. Two C-H center dot center dot center dot O interactions involving benzylic C-H hydrogens activated by the electron-withdrawing character of the o-carborane cage and the oxygen atom of the acetone seem to be the most important. DFT calculations indicate that the binding energy for entrapment of acetone is 6.6 kcal/mol. Inclusion of acetone is achieved through not only multiple C-H center dot center dot center dot O interactions but also a number of C-H center dot center dot center dot pi interactions. The third benzyl-o-carborane moiety is fixed in the syn conformation by intramolecular and intermolecular C-H center dot center dot center dot pi interactions.

  A nickel‐catalyzed arylation at the carbon center of o‐carborane cages has been developed, thus leading to the preparation of a series of 1‐aryl‐o‐carboranes and 1,2‐diaryl‐o‐carboranes in high yields upon isolation. This method represents the first example of transition metal catalyzed C,C′‐diarylation by cross‐coupling reactions of o‐carboranyl with aryl iodides.

B3LYP/6-31G∗ computations have been carried out on compounds 2 and 4, on 4,4′-bis(ortho-carboranyl)biphenyl 6 and on 1,2-bis(1′-ortho-carboranyl)benzene 7. Those on 2, 4 and 6 show the computed geometries to be in very good agreement with the experimental geometries: those on 7 allowed the reported molecular geometry of this compound to be revised
