Pyridine and benzonitrile adducts of bis(4-nonafluorobiphenyl)zinc
摘要:
Treatment of (Ar-F')(2)Zn(OEt2)(2) (Ar-F' = 4-C6F5C6F4) with 2 equiv. of benzonitrile, 4-(phenyl)benzonitrile, 4(pyrrolyl)benzonitrile, pyridine, 4-(phenyl)pyridine or 4-(pyrrolyl)pyridine in dichloromethane afforded the corresponding adducts (Ar-F')(2)ZnL2 in near quantitative yield. The 2,2'-bipyridine adduct was prepared similarly. Multinuclear NMR spectroscopy indicated that zinc's four-coordinate character was maintained in solution. The pyridine complex crystallized from dichloromethane with a solid-state structure free of face-to-face aryl-aryl interactions. In contrast, the 4-(pyrrolyl)pyridine adduct crystallized from both dichloromethane and 1,2-difluorobenzene, with solvent of crystallization, but otherwise essentially identical supramolecular architectures assembled through aryl-aryl synthons, including a face-to-face pentafluorophenyl-pyrrole interaction.
