Cycloheptatrienyl, alkyl and aryl PCP-pincer complexes: Ligand backbone effects and metal reactivity

Pincer complexes have developed into a class of compounds with a tremendous breadth of applications in organometallic chemistry and catalysis. In this article we have selected a few PCP-pincer ligand systems and demonstrate that small changes in the ligand backbone have a dramatic impact on the reactivity change of their metal complexes.
