For a series of ferrocenyl thiophenes of type Fe(eta5-C5H4-(4-R-cC4H2S-3-yl))(eta5-C5H4-(C6H3-3,5-(CF3)2) [R = H (3a), OMe (4a)], Fe(eta5-C5H4-(4-R-cC4H2S-3-yl)(eta5-C5H4-CHO) [R = H (3b), OMe (4b)], and Fe(eta5-C5H4-(4-R-cC4H2S-3-yl)(eta5-C5H4-C?N) [R = H (3c), OMe (4c)], the influence of electron-withdrawing substituents at the ferrocenyl moiety and electron-donating groups at the thiophene unit on the electronic behavior of 3a-c and 4a-c is reported. The coupling of the ferrocenyl and the thiophene moieties has been realized using the Negishi C,C cross-coupling reaction protocol. Compounds 3a and 4c were structurally characterized by single-crystal X-ray diffraction studies. In electrochemical measurements the ferrocenyl redox potential depends on the particular substitution at the ferrocenyl and the thiophene unit. Moreover, UV/Vis/NIR studies showed ligand-to-metal charge transfer (LMCT) interactions, which occur after oxidation and are shifted bathochromically as the donor-acceptor energy gap decreases. Using different substituents, possessing electron-withdrawing or donating capabilities, allows adjusting the energy difference between the ferrocenium-acceptor unit and the donating thiophene system.

[1.1.1]Propellane is a highly strained tricyclic hydrocarbon whose reactivity is dominated by addition reactions across the central inverted bond to provide bicyclo[1.1.1]pentane derivatives. These reactions proceed under both radical and two-electron pathways, hence, providing access to a diverse array of products. Conversely, transition metal-catalyzed reactions of [1.1.1]propellane are underdeveloped and lack synthetic utility, with reported examples generally yielding mixtures of ring-opened structural isomers, dimers, and trimers, often with poor selectivity. Herein, we report that nickel(0) catalysis enables the use of [1.1.1]propellane as a carbene precursor in cyclopropanations of a range of functionalized alkenes to give methylenespiro[2.3]hexane products. Computational studies provide support for initial formation of a Ni(0)-[1.1.1]propellane complex followed by concerted double C-C bond activation to give the key 3-methylenecyclobutylidene-nickel intermediate.

The electrospray ionization behavior of some ferrocenylalkylazoles CpFeC5H4CH(R)Az (AzH are derivatives of imidazole, pyrazole, triazole and their benzo analogs; R = H, Me, Et, Ph), ferrocenylalkanols CpFeC5H4CH(R)OH (R = H, Me), and mixtures of the latter with azoles was studied. The electrospray ionization mass spectra of these compounds, in addition to the molecular ion [M] +·, the protonated molecule [M + H]+, and ferrocenylalkyl cation [FcCHR]+ peaks, exhibit also intensive peaks for the binuclear ions [(FcCHR)2X]+ (X = Az or O), resulting from ferrocenylalkylation of the initial compounds with the ferrocenylalkyl cations. Electrospray ionization of an equimolar mixture of ferrocenylmethanol FcCH2OH and imidazole gives the protonated ferrocenylmethylimidazole molecule [FcCH2Im + H]+ and the [FcCH2(Im)2 + H]+ dimer, apart from the ions typical of each component, i.e., ferrocenylalkylation of azoles with the ferrocenylalkylcarbinols, known in the chemistry of solutions, takes place under electrospray conditions.

Further advances in understanding the mechanism of action of resveratrol and its application require new analogs to identify the structural determinants for the cell proliferation inhibition potency. Therefore, we synthesized new trans-resveratrol derivatives by using the Wittig and Heck methods, thus modifying the hydroxylation and methoxylation patterns of the parent molecule. Moreover, we also synthesized new ferrocenylstilbene analogs by using an original protective group in the Wittig procedure. By performing cell proliferation assays we observed that the resveratrol derivatives show inhibition on the human colorectal tumor SW480 cell line. On the other hand, cell viability/cytotoxicity assays showed a weaker effects on the human hepatoblastoma HepG2 cell line. Importantly, the lack of effect on non-tumor cells (IEC18 intestinal epithelium cells) demonstrates the selectivity of these molecules for cancer cells. Here, we show that the numbers and positions of hydroxy and methoxy groups are crucial for the inhibition efficacy. In addition, the presence of at least one phenolic group is essential for the antitumoral activity. Moreover, in the series of ferrocenylstilbene analogs, the presence of a hidden phenolic function allows for a better solubilization in the cellular environment and significantly increases the antitumoral activity.

Ferrocenyl-nucleobases are an increasingly important class of complexes with possible applications in biology, pharmacy and material sciences. This review focuses on synthetic methods for ferrocenyl-nucleobases and on the chemical transformations of these compounds. Utilization of ferrocenyl-nucleobases for self-assembly material preparation and as building blocks for XNA synthesis and anticancer and antibacterial agents is also discussed herein. This review shows that the combination of the redox-active biologically artificial ferrocenyl moiety and genetically essential nucleobases leads to conjugates that retain their electrochemical and self-pairing properties. These properties make ferrocenyl-nucleobases attractive objects for further studies and for applications across the entire spectrum of physico-chemical and engineering sciences.
