Front Cover: Synthesis and Applications of Ferrocene‐Fused Nitrogen Heterocycles (Eur. J. Inorg. Chem. 8/2022)

Abstract

The Front Cover shows the fusion of ferrocene and heterocyclic compounds (exemplified by pyridine). The chemistry of ferrocene‐fused nitrogen heterocycles has recently become an exciting field of research. From a synthetic point of view, the transfer to ferrocene of some of the powerful transition‐metal‐catalyzed methodologies developed for the C−H bond functionalization of benzene derivatives has no doubt contributed to this extraordinary development. Moreover, because of the planar chirality most of these ferrocene‐fused systems exhibit, some of them have found interesting applications as organocatalysts in asymmetric catalysis. In this review, we showcase recent advances in the synthesis and applications of this type of fused systems. The cover was designed by Illan López. More information can be found in the Review by L. A. López and co‐workers.

Forever young: the first seventy years of ferrocene

“…At this point, however, it must be noted that not only heterocyclic carbenes but also native, ferrocene-fused heterocycles are used in catalysis, as exemplified by the planar-chiral, ferrocene-fused pyridine derivatives. 153…”

Synthesis, Characterization, Electrochemical Properties and Antimicrobial Activity of Schiff Bases and Benzimidazoles Including Ferrocene Group and Their CoCl2 Complexes

“…Recently, researchers have shown great interest in heterocyclic compounds containing ferrocene due to their potential applications as sensitive electrochemical sensors [1,2] , nonlinear optical materials [3] , antitubercular, antibacterial and anticancer drugs [4][5][6] , catalysts [7,8] and redox fluorescent switches [9] . This is due to the unusual features of the ferrocene group which can modify the heterocyclic moiety with its particular chemical behavior [10][11][12] .…”

Thermal and thermo-oxidative stability of a series of palladium and platinum ferrocenylamine sulfides and selenides

“…11 Their complexes are widely used as catalysts in various organic reactions for example, selective hydrogenation, 12–15 cross–coupling reactions, 12,16,17 and for the synthesis of ferrocene-fused heterocycles. 18 The special structure of chiral ferrocenylamines is useful in stereoselectivity, for example, asymmetric hydrogenation, 19 hydrosilylation, 3,5 aldol reactions, 20 cycloaddition, 10 allylic alkylation, 7 C–H arylation, 4 and double C–H functionalization, 21 as well as for electrochemical enantiodifferentiation. 22 Industrial applications involve production of redox–active anion sensors, 23 supercapacitor electrodes, 24 corrosion inhibitors, 25 and electro- and photo-responsive materials.…”
