“…Both forms were catalytically active in the hydrogen transfer reaction of benzophenone with iso-propanol. Moreover, the two species can be converted to conducting metallopolymer thin films similarly to previously reported thiophene derivatives of functionalized salen [58] (Figure 2). Cyclic (alkyl)(amino) carbenes (CAACs) differ from "classical" N-heterocyclic carbenes (bearing two nitrogen atoms adjacent to the carbene centre) in that they possess only one amino substituent, while the other was replaced by an sp 3 carbon atom in an alkyl group.…”

Rhodium is one of the most used metals in catalysis both in laboratory reactions and industrial processes. Despite the extensive exploration on “classical” ligands carried out during the past decades in the field of rhodium-catalyzed reactions, such as phosphines, and other common types of ligands including N-heterocyclic carbenes, ferrocenes, cyclopentadienyl anion and pentamethylcyclopentadienyl derivatives, etc., there is still lively research activity on this topic, with considerable efforts being made toward the synthesis of new preformed rhodium catalysts that can be both efficient and selective. Although the “golden age” of homogeneous catalysis might seem over, there is still plenty of room for improvement, especially from the point of view of a more sustainable chemistry. In this review, temporally restricted to the analysis of literature during the past five years (2015–2020), the latest findings and trends in the synthesis and applications of Rh(I) complexes to catalysis will be presented. From the analysis of the most recent literature, it seems clear that rhodium-catalyzed processes still represent a stimulating challenge for the metalloorganic chemist that is far from being over.

“…As such, various structures and applications are feasible due to the broad spectrum of electropolymerizable monomeric thiophene-containing metal complexes. [20][21][22][23] Complexes featuring N 2 O 2 -tetradentate Schiff bases ligands have gained interest in the field of coordination chemistry [24][25][26] due to their impressive number of applications in different areas, 27 such as in non-linear optics, 28 biological chemistry, 29 and catalysis. 30,31 Besides, structural and electronic modifications over the Schiff base ligands bestow great versatility to the system in altering the architecture by modifying the substituents placed in the ligands.…”
