Summary: In this study, three Ru(II) arene complexes with a bidentate benzimidazole-based ligand were synthesized and their antitumor activity was studied by varying the co-ligand X. The synthesized compounds showed good interactions with serum albumin proteins, had good drug stability and lipophilic character. They were found to bind with DNA and could induce apoptosis in cancer cells, as well as upregulate cleaved caspase-3 expression and downregulate BCLXL expression. These findings provide a new direction for the investigation of antitumor ruthenium-based metallodrugs using benzimidazole-based ligands.

Summary: In this study, diruthenium-based cyanido-bridged asymmetrical compounds were used to investigate the electron transfer process. A series of new trinuclear complexes were synthesized and characterized, and their electron transfer properties were analyzed through UV-vis-NIR spectroscopy. The results show that increasing the electron-accepting capability of the electron acceptor is more effective in decreasing the electron transfer energy.

Summary: Compared to phosphine counterparts, little attention has been paid to the study of ferrocene stibines. This paper describes the synthesis of ferrocene stibine derivatives and their reactivity and coordination behavior. The compounds were characterized through various spectroscopic techniques and crystallography. The research findings reveal important insights into the structural parameters and electrochemical properties of the ferrocene stibines, but their catalytic efficiency needs to be further improved in Suzuki-Miyaura biaryl coupling reactions.

Summary: Substituents were found to affect the properties of ferrocene acylphosphines, with the increasing donor ability of the substituents leading to higher basicity of the phosphine groups. Catalysts derived from acylphosphines with electron-donating aliphatic substituents showed the highest reaction yields in Au-catalysed alkyne hydration and intramolecular cyclisation reactions. The carbonyl moiety in the acylphosphines appeared to reduce steric crowding around the phosphorus atom and counterbalanced the electron-donating effect of the ferrocenyl moiety.
