“…Apart from gaining insight into the coordinative properties of ligands 26 and 30 (cf. subsection ), certain complexes were probed for behavior in catalysis or bioassays. The first example of the biological evaluation of Ag(I) and Cu(I) quaterpyrdine complexes for their cytotoxic properties should be highlighted (cf.…”

Quaterpyridine (qtpy) ligands have found significant applications as N-heterocyclic scaffolds in self-assembly processes, in particular the formation of various metallosupramolecular architectures, limited, however, by difficulties in their synthesis. Recent progress in the preparative organic and organometallic chemistry of polypyridines has resulted in the elimination of the most serious drawbacks concerning qtpy synthesis, consequently giving rise to a renewed interest in this class of compounds. Herein, we endeavor to define the essential aspects of quaterpyridine chemistry and provide the reader with a perspective on the ways in which this field has begun to flourish.

“…Our previous studies on the coordination properties of dimethylquaterpyridine self-assembled with transition metal ions have resulted in a broad spectrum of architectures, including mono-and poly-nuclear complexes with octahedral metal ions [32][33][34] as well as organometallic 35 and helical complexes. 36 Simultaneously, our recent studies on the terpyridine complexes of silver(I) 37 became the inspiration for the design of new helicates of silver(I) and copper(I) with 6,6 0 0 0 0 -dimethyl-2,2 0 ;6 0 ,2 00 ;6 00 ,2 0 0 0 -quaterpyridine L (Fig.…”

“…No experimental conditions for the synthesis were provided by the authors. The rollover complex 136 , isolated and characterized by means, inter alia, of X-ray crystallography, showed to be a highly selective catalyst precursor in the hydrosilylation of styrene and terminal alkynes ( Figure 67 ) [ 125 ].…”

Rollover Cyclometalation as a Valuable Tool for Regioselective C–H Bond Activation and Functionalization

Rollover cyclometalation constitutes a particular case of cyclometallation reaction. This reaction occurs when a chelated heterocyclic ligand loses its bidentate coordination mode and undergoes an internal rotation, after which a remote C–H bond is regioselectively activated, affording an uncommon cyclometalated complex, called “rollover cyclometalated complex”. The key of the process is the internal rotation of the ligand, which occurs before the C–H bond activation and releases from coordination a donor atom. The new “rollover” ligand has peculiar properties, being a ligand with multiple personalities, no more a spectator in the reactivity of the complex. The main reason of this peculiarity is the presence of an uncoordinated donor atom (the one initially involved in the chelation), able to promote a series of reactions not available for classic cyclometalated complexes. The rollover reaction is highly regioselective, because the activated C–H bond is usually in a symmetric position with respect to the donor atom which detaches from the metal stating the rollover process. Due to this novel behavior, a series of potential applications have appeared in the literature, in fields such as catalysis, organic synthesis, and advanced materials.
