In chemistry, a transition metal pincer complex is a type of coordination complex with a pincer ligand. Pincer ligands are chelating agents that binds tightly to three adjacent coplanar sites in a meridional configuration.

Pincer ligands are chelating agents that bind tightly to three adjacent coplanar sites of a metal complex. Stoichiometric and catalytic applications of pincer complexes have been studied at an accelerating pace since the mid-1970s.

Jan 15, 2023 · In this review, we highlight the remarkable features of pincer-ligated metal complexes and their growing capacity to act as catalysts in C H activation chemistry. The review summarizes the diversity in choice of ligand–metal duo, the advantage of a robust yet flexible pincer skeleton, the harmonious relation of the metal centre and a non ...

Mar 15, 2018 · In homogenous catalytic transformations, pincer ligands provide enhanced chemical and thermal stability which serve to minimize the leaching of the metal during the catalytic cycle. These ligands also offer the ability to fine tune the electronic and the steric properties about the metal center, thereby increasing the scope of their applications.

Jan 1, 2021 · In this chapter, a general view of group 10 (Ni, Pd, and Pt) pincer metal complexes including synthetic methodologies and their promising applications in the recent years are presented.
