In 2005, a facile dihydrogen activation was reported by the Power group using an alkyne analog of germanium [ArGe≡GeAr; Ar=2,6‐Trip2‐C6H3 (Trip=2,4,6‐iPr3‐C6H2)]. After that, a significant progress has been made in the activation of various small molecules by main‐group compounds, and a variety of stoichiometric and catalytic processes have been formulated using the p‐block elements. In this regard, compounds containing low‐valent main‐group elements with a frontier orbitals of relatively small energy gaps or compounds forming frustrated Lewis pair (FLP) became quite successful. In spite of these promising stoichiometric and catalytic transformations, redox‐cycling catalysts based on main‐group elements remain extremely rare. Recently, it has been observed that pincer type ligands supported geometry constrained main‐group compounds are capable of acting as redox catalysts similar to those of the transition metals. In this review, we focus on the synthesis and the structural aspects of the geometry constrained main‐group compounds using pincer ligands. Emphasis has been placed on their applications on catalytic activity and small molecules activation.

非VSEPR主族化合物的钳型配体辅助催化和小分子活化。

2005年,Power集团报告了使用锗的炔烃类似物[ArGe≡GeAr; Ar = 2,6‐Trip 2 ‐ C 6 H 3(Trip = 2,4,6i Pr 3‐ C 6 H 2)]。此后,通过主基团化合物激活各种小分子方面已取得了重大进展,并且使用p构筑了各种化学计量和催化过程。块元素。在这方面,包含低价主族元素且能隙相对较小的前沿轨道的化合物或形成受阻路易斯对(FLP)的化合物已相当成功。尽管有这些有希望的化学计量和催化转化,但基于主族元素的氧化还原循环催化剂仍然极为罕见。最近,已经观察到夹钳型配体支持的几何形状受约束的主族化合物能够像过渡金属一样用作氧化还原催化剂。在这篇综述中,我们集中在使用钳形配体的几何受约束的主族化合物的合成和结构方面。重点放在其在催化活性和小分子活化上的应用上。
