Cooperative Reactivity by Pincer-Type Complexes Possessing Secondary Coordination Sphere

Pincer complexes represent a family of potent compounds having a tremendous number of manifold applications in organometallic chemistry, synthesis, catalysis, materials science, and bioinorganic chemistry. This chapter overviews the recent developments in the chemistry and catalytic applications of pincer complexes incorporating secondary coordination sphere or an appended functionality that can interact with the catalytic center or can modulate its reactivity via secondary substrate-catalyst interactions. Combining the concepts of modular and stable pincer ligands and secondary interactions provides excellent opportunities for fine-tuning the properties of a coordinated metal center and, consequently, attracts considerable interest.
