描述 已合成具有 Be-Be 键的稳定有机金属化合物 几十年来，对含有无支撑同原子金属-金属 (M-M) 键的有机金属化合物的研究一直是人们主要关注的领域。这些化合物具有独特的、否则难以接近的键合，例如 M-M 四重键和五重键，以及令人着迷的反应性，包括模仿 C-C 多重键的反应。最终，该领域研究的主要驱动力是突破给定元素的键合界限，并在此过程中重写教科书。在本期第 1147 页，Boronski 等人。 (1)报告了二茂基茂的分离作为该领域的最新进入者。二铍茂是一种稳定的铍-铍键合化合物，是一种相对容易获得的亲核铍来源，有潜力释放有机铍与大量新底物的反应性。
Description A stable organometallic compound with a Be-Be bond has been synthesized The investigation of organometallic compounds containing unsupported homoatomic metal-metal (M-M) bonds has been an area of major interest for decades. These compounds feature distinct, otherwise inaccessible bonding, such as M-M quadruple and quintuple bonds, and fascinating reactivity, including mimicking the reactions of C-C multiple bonds. Ultimately, the main driver for research in this area is to push the boundaries of bonding for a given element and, in doing so, rewrite the textbooks. On page 1147 of this issue, Boronski et al. (1) report the isolation of diberyllocene as the latest entrant in the field. Diberyllocene is a stable Be-Be bonded compound and is a relatively accessible source of nucleophilic beryllium, which has the potential to unlock the reactivity of organoberyllium with a vast array of new substrates.
