The development of synthetic chemistry since the early 1900s owes much to the service of organolithium reagents. Brilliant bases (e.g., deprotonating C-H bonds), nucleophiles (e.g., adding to unsaturated molecules), and transfer agents (e.g., delivering ligands to other metals), these versatile virtuosi and to a lesser extent the organic derivatives of the other common alkali metals sodium and potassium have proved indispensable in both academia and technology. Today these monometallic compounds are still utilized widely in synthetic campaigns, but in recent years they have been joined by an assortment of bimetallic formulations that also contain an alkali metal but in company with another metal. These bimetallic formulations often exhibit unique chemistry that can be interpreted in terms of synergistic effects, for which the alkali metal is essential, though it is often the second metal that performs the synthetic transformation. Here, this "alkali-metal-mediated" chemistry is surveyed focusing mainly on bimetallic formulations containing two alkali metals or an alkali metal paired with magnesium, calcium, zinc, aluminum, or gallium. In this International Year of the Periodic Table (IYPT), we ponder whether a Pairiodic Table of Element Pairs will emerge in the future.

碱金属介导的极性主族有机金属化学中的协同效应。
自1900年代初以来合成化学的发展很大程度上归功于有机锂试剂的使用。出色的碱(例如,去质子化的CH键),亲核试剂(例如,添加到不饱和分子中)和转移剂(例如,将配体传递到其他金属上),这些多功能的维他命和(在较小程度上)其他常见碱金属的有机衍生物钠和钾已被证明在学术界和技术界都是必不可少的。如今,这些单金属化合物仍广泛用于合成活动中,但近年来,它们又加入了各种双金属配方,这些配方也含有碱金属,但与另一种金属结合在一起。这些双金属配方通常表现出独特的化学性质,可以用协同作用来解释,碱金属是必不可少的,尽管它通常是第二种进行合成转化的金属。在此,对这种“碱金属介导的”化学物质的研究主要集中在含有两种碱金属或与镁,钙,锌,铝或镓配对的碱金属的双金属配方中。在这个国际元素周期表年(IYPT)中,我们考虑将来元素对的成对表是否会出现。
