Coordination Versatility of sp3-Hybridized Pincer Ligands toward Ligand–Metal Cooperative Catalysis

Pincer-type complexes occupy a very important position in chemistry and chemistry-related disciplines. In this article we have selected several spectacular examples of pincer systems and demonstrate that reversible structural changes in the ligand backbone may have a dramatic impact on the reactivity of their metal complexes. This perspective aims to focus on some recent exciting developments in the chemistry of “cooperating” PN(sp 3 )P and PC(sp 3 )P pincer ligands relevant to catalytic applications.
