ABSTRACT

Herein, a novel ferrocene-rhodamine receptor conjugated with an allylimine bridge was facilely synthesized. This triple channel receptor can selectively and sensitively monitor Pd2+ ions through chromogenic, fluorogenic and electrochemical assays in aqueous medium with a low detection limit (8.46 × 10-9 M) and a fast response (<8 min). It can be applied as a fluorescent probe for effective survey of Pd2+ ions in living cells. Moreover, a plausible recognition mode was proposed and rationalized by theoretical calculations.

ABSTRACT

An efficient and green synthesis of 4-ferrocenylquinoline derivatives through a TsOH-catalyzed three-component reaction of aromatic aldehydes, amines and ferrocenylacetylene in water has been successfully developed. This strategy is a powerful method for the construction of diverse ferrocenyl-quinoline conjugates from simple available starting materials as it minimized the use of metal catalyst and organic solvent in the reaction process. The conjugates feature unique structures and excellent electronic properties. Moreover, a plausible mechanism for this TsOH-catalyzed three-component reaction was proposed and assessed.

ABSTRACT

Ten ferrocenyl bis-amide derivatives were successfully synthesized via the Ugi four-component reaction by treating ferrocenecarboxylic acid with diverse aldehydes, amines, and isocyanides in methanol solution. Their chemical structures were fully characterized by IR, NMR, HR-MS, and X-ray diffraction analyses. They feature unique molecular morphologies and create a 14-membered ring motif in the centro-symmetric dimers generated in the solid state. Moreover, the electrochemical behavior of these ferrocenyl bis-amides was assessed by cyclic voltammetry.
