Abstract In this short review, different phenomena that are triggered by the interaction of different compounds or clusters of compounds with electron-deficient systems, in particular beryllium and boron compounds, have been discussed in some detail. Particular attention was devoted to the huge acidity enhancements that can be induced through the interaction of conventional bases with B or Be containing compounds, which change these conventional bases in extremely strong proton donors. We have paid also attention to the cooperativity between Be bonds with other weak interactions, which results in a substantial increase of their strength, that can lead in some specific cases to the spontaneous formation of ion-pairs in the gas phase. Finally, the behavior of different Be derivatives as electron and anion sponges is discussed as well as the conditions needed to have clusters exhibiting rather strong Be–Be bonds, even though the Be–Be interaction in Be2 dimer is extremely weak. Finally, some attention was paid to systems with extremely short Be–Be distances but without a bond.

缺电子系统周围丰富化学的一些有趣特征

摘要 在这篇简短的综述中,已经详细讨论了由不同化合物或化合物簇与缺电子系统(特别是铍和硼化合物)相互作用引发的不同现象。特别关注可以通过常规碱与含 B 或 Be 化合物的相互作用引起的巨大酸度增强,这在极强的质子供体中改变了这些常规碱。我们还注意到 Be 键与其他弱相互作用之间的协同性,这导致它们的强度大幅增加,在某些特定情况下会导致气相中离子对的自发形成。最后,讨论了不同 Be 衍生物作为电子和阴离子海绵的行为,以及使簇表现出相当强的 Be-Be 键所需的条件,即使 Be2 二聚体中的 Be-Be 相互作用非常弱。最后,对 Be-Be 距离极短但没有键的系统给予了一些关注。
