“…The field of pyrazole ligands and their organometallic derivatives is very large, and several book chapters and reviews have been devoted to it. [1][2][3][4] We have summarized in Table 1 a select group of silver(I) complexes reported in the literature. In fact, more than 20 different pyrazolates have been used to prepare Ag(I) complexes.…”

This work reports the calculation of the nuclear magnetic resonance (NMR) chemical shifts of eight trinuclear Ag(I) complexes of pyrazolate ligands using the relativistic program ZORA. The data from the literature concern exclusively 1H, 13C, and 19F nuclei. For this reason, one of the complexes that is derived from 3,5‐bis‐trifluoromethyl‐1H‐pyrazole has been studied anew, and the 15N and 109Ag chemical shifts determined for the first time in solution. Solid‐state NMR data of this compound have been obtained for some nuclei (1H, 13C, and 19F) but not for others (14N, 15N, and 109Ag).

“…32 ''Rollover'' cyclometalation is historically connected with the enormously popular 2,2 0 -bipyridine (bipy) ligand that was described by Blau already in 1888 33,34 and which, over the ensuing decades, has attracted growing interest. [35][36][37][38][39][40][41][42] Actually, a review article was even entitled ''Bipyridine: The Most Widely Used Ligand'' 36 and also chiral derivatives of 2,2 0 -bipyridine were developed. 43,44 The attractiveness of this ligand is certainly a consequence of i) its rich and intriguing coordination chemistry, ii) the easiness of functionalization of the pyridine rings and iii) the high stability of many of its transition-metal complexes against moisture and oxygen.…”

“Rollover” cyclometalation – early history, recent developments, mechanistic insights and application aspects

2012

''Rollover'' cyclometalation constitutes a special case among the well-known class of cyclometalation reactions. An overview is given that covers the very first description of this reaction type, as well as recent developments. In addition, not only condensed-phase experiments are reviewed, but also investigations based on mass spectrometric techniques, together with ''in silico'' studies using DFTbased calculations are considered. While the latter two methods allow for a detailed analysis of the intrinsic factors that affect the reaction mechanisms, consideration of all three regimes permits to develop a coherent mechanistic picture and to address the often noted gap between condensed-and gasphase studies. Moreover, the quite unexpected reactivity of ''rollover'' cyclometalated complexes in gasphase experiments, as well as potential applications, e.g. in synthetic procedures, are discussed in some detail.

“…Thanks to the remarkable advances achieved in organic synthesis, these fantastic molecular metalloconstructions, capable of creating complex ligands, as many as desired, are to a greater or lesser degree preorganized for templating and self-assembly. Diversified polypyridine ligands [202][203][204], on repeated occasions noted above, testify to this fact. Also, the aesthetic desires of the many researchers, as driving forces in the creation of metallosupramolecular arabesques blending the splendid with the rational, cannot be ignored.…”
