The Lewis acidity of boron in diboradiferrocene 1 is strongly enhanced through oxidation of the iron atoms as evident from examination of X-ray structural parameters of the mixed-valent cation 1(+)PF(6) and further confirmed from the strong complexation of MeCN to the dication in 2(2+)(I(3))(2).
通过对混合价阳离子1(+)PF(6)的X射线结构参数的研究可以明显看出,二硼二茂铁1中硼的路易斯酸性通过铁原子的氧化而得到显著增强,并且在2(2+)(I(3))(2)中乙腈与二价阳离子的强络合作用进一步证实了这一点。
