富电子的晚期金属和正电性主族元素（金属和类金属）可以结合起来，为探索金属-配体合作提供一个两亲性的外观，但金属/主族键的不稳定性经常限制了这些单元的研究和应用。将主族供体插入钳形框架中，在那里它们被稳定并保持在过渡金属伙伴附近，可以允许发现新的反应性模式和并入催化过程。该观点总结了具有金属/主基团键的钳形框架所证明的协同性的常见模式，突出了硼，铝和硅供体之间的相似性，并确定了进一步发展的方向。
Electron-rich late metals and electropositive main-group elements (metals and metalloids) can be combined to provide an ambiphilic façade for exploring metal–ligand cooperation, yet the instability of the metal/main-group bond frequently limits the study and application of such units. Incorporating main-group donors into pincer frameworks, where they are stabilized and held in proximity to the transition-metal partner, can allow discovery of new modes of reactivity and incorporation into catalytic processes. This Perspective summarizes common modes of cooperativity that have been demonstrated for pincer frameworks featuring metal/main-group bonds, highlighting similarities among boron, aluminium, and silicon donors and identifying directions for further development.
