Abstract

Interaction of perfluorinated group 13 element Lewis acids E(C₆F₅)₃ (E=B, Al, Ga, In) and Al{OC(CF₃)₃}₃ with diatomic halogens and interhalogens was studied computationally. Boron-containing derivative is predicted to form weak complexes with halogens and to be thermodynamically stable with respect to iodination, while its heavier derivatives form stronger complexes that are unstable with respect to E−C bond oxidation. The reactivity of E(C₆F₅)₃ with iodine and iodine monochloride and Al{OCR₃}₃ (R=CF₃, C₆F₅) with iodine was explored experimentally. Experimental data confirm that B(C₆F₅)₃ does not react with ICl at room temperature and with molecular iodine in temperature range 233–350 K. Heavier group 13 element derivatives E(C₆F₅)₃ upon reaction with I₂ and ICl undergo oxidation processes with C₆F₅I evolution. Both Al{OC(CF₃)₃}₃*C₆H₅F and Al{OC(C₆F₅)₃}₃ do not form stable complexes with molecular iodine.

全氟13族路易斯酸与双原子卤素和卤间素的相互作用：计算和实验研究

计算研究了全氟13族元素路易斯酸E(C6F5)3 （E=B, Al, Ga, In）和Al{OC(CF3)3}3与双原子卤素和间卤素的相互作用。含硼衍生物与卤素形成弱配合物，在碘化方面热力学稳定，而其较重的衍生物形成较强的配合物，在E−C键氧化方面不稳定。实验考察了E(C6F5)3与碘、一氯化碘和Al{OCR3}3 （R=CF3, C6F5）与碘的反应性。实验数据证实，B(C6F5)3在室温下不与ICl反应，在233 ~ 350k范围内不与碘分子反应。较重的13族元素衍生物E(C6F5)3与I2和ICl反应后，随着C6F5I的演化而发生氧化过程。Al{OC(CF3)3}3*C6H5F和Al{OC(C6F5)3}3都不能与分子碘形成稳定的配合物。
