本文首次提出了“内鋰键”存在的可能性,并提出了三点有关的看法。根据这三点看法,我们设计了一些含“内鋰键”的化合物,并观察了这些有机鋰化合物的红外光谱和紫外光谱。我们发现“内鋰键”能像内氢键一样地存在于分子之中。最后,我们用CNDO/Ⅱ法对这些化合物作了计算,计算结果也证明了在这些分子中“内鋰键”存在的可能性。 This paper presents for the first time the possibility of the existence of “internal lithium bond” and puts forward three relevant views. Based on these three observations, we have designed some compounds with “internal lithium bonds” and observed the IR and UV spectra of these organolithium compounds. We find that “internal lithium bonds” can exist in the molecule like internal hydrogen bonds. Finally, we calculated these compounds using the CNDO / II method and the calculations also demonstrated the possibility of “lithium-internal bonds” in these molecules.
