Recent Advances in Catalysis with Transition‐Metal Pincer Compounds

Abstract

Pincer complexes are useful tools for organic synthesis. Their high stability and easy functionalization have allowed the development of novel catalytic systems that have had a tremendous impact in different areas of chemistry. Thus, catalytic reactions are nowadays a fundamental part of several synthetic routes, as they allow “greener” procedures with high atom efficiency. In this context, pincer complexes have contributed to the establishment of novel and efficient catalytic reactions. Thus, herein we summarize the most recent relevant advances involving pincer complexes as catalysts.

Catalytic and antibacterial properties of 3‐dentate carboxamide Pd/Pt complexes obtained via a benign route

“…Various reactions for forming a C–C bond are currently under study because of their significant applications . Among them, the Mizoroki–Heck reaction is, perhaps, the most strategic process for the arylation of olefins through palladium‐catalyzed C–C formation reactions . Although numerous attempts at designing a green, simple, cost‐effective, and efficient approach for this reaction have been made, there is still ample scope for improvement.…”

Phosphine Ligand‐Free Ruthenium Complexes as Efficient Catalysts for the Synthesis of Quinolines and Pyridines by Acceptorless Dehydrogenative Coupling Reactions

“…Among various homogeneous transition metal catalysts, Ru-complexes are the most efficient reported to date. [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][60][61][62][63] Metal-ligand cooperative catalysis [64][65][66][67] can dramatically improve catalytic performance of ADC reactions using pincer ligands bearing NH, OH or CH 2 functionality. [40][41][42][43][44][68][69][70][71][72][73][74][75][76][77][78][79][80][81] Milstein, [40] Sun, [41] Yu, [42] Kundu [43] and Chen [44] have independently developed bifunctional Ru(II) catalysts for the synthesis of pyridine and quinoline derivatives (Scheme 1), b...…”

A Nickel Complex Containing a Pyramidalized, Ambiphilic Pincer Germylene Ligand

“…Transition metal complexes with pincerl igands have attracted considerable attention because of their ability to activates mall molecules as well as their highc atalytic activity. [1] Those possessing al ow-valent electropositive elements uch as silicon(II) at the central coordination site are especially interesting because their electropositivee lement-transition metal bond is expected to be strongly polarized and the electropositive element center shows high electrophilicity. [2] There are several exampleso fP SiP-typep incer complexes having silicon(II)a tt he central coordination site that are highly reactive.…”
