Metal complexes with ‘pincer’-type ligands incorporating N-heterocyclic carbene functionalities

Secondary Thioamides as Multidentate Ligands for Functional Metal Complexes

“…However, from the early stage of "Pincer Chemistry," in the mid-70's, a large variety of pincer-named complexes has been reported; for instance, dianionic C^N^C pincer complexes, 21 nonmeridional (facial) pincer complex, 22,23 and heteroaromaticcentered pincer complexes; 13,22,23 these are not included in the classical definition of pincer. Hence, for the sake of clarity, here we will use the term "pincer" in a wider sense as shown in Figure 2b.…”

Neutral Tridentate PNP Ligands and Their Hybrid Analogues: Versatile Non‐Innocent Scaffolds for Homogeneous Catalysis

“…These ligands offer complementary chemistry to their monoanionic derivatives, for example, when focusing on low-valent metal centers (e.g., Rh I or Ir I ) or if coordinatively unsaturated dicationic complexes (such as Pt II ) are targeted. These ligands range from the ubiquitous 2,2',6',2''-terpyridine [23] (tpy, 6 in Figure 2) to bis-(imino)pyridine systems 7, studied for late-transition-metal alkene polymerizations, [24] and related pyridine-based scaffolds such as 8 [25] and 9. [26] Other neutral tridentate frameworks, including structures 10 [27] and 11, [28] have also recently been developed, but little emphasis has so far been placed on catalytic applicability of these systems.…”
