“…1 However oxidative addition of dithietes and disulfides to lower oxidation state metals has proved an alternative if not extensively used synthetic strategy. 8,25 For example, recent studies by Corrigan and co-workers revealed oxidative addition of cyclic disulfides to Pt(PPh 3 ) 4 occurred in moderate isolated yield (ca. 50%) after stirring at ambient temperature for 20 h. 25 In our current studies we have investigated tetrathiocines as a readily accessible alternative to dithiete and disulfides.…”

Oxidative addition of the electron-rich tetra-methoxy-dibenzo-1,2,5,6-tetrathiocine [(MeO)2C6H2S2]2 to zero-valent group 10 transition metal complexes in the presence of diphenylphosphinoethane (dppe) affords the corresponding dithiolate complexes, [(DMOBD)M(dppe)] (DMOBD = dimethoxybenzenedithiolato, (MeO)2C6H2S2(2-); M = Ni, Pd, Pt) in high yield which were characterized by single crystal X-ray diffraction. Whereas the Pd and Pt complexes exhibit two quasi-reversible 1e(-) oxidation processes, the nickel species undergoes a quasi-reversible 1e(-) reduction.

“…The incorporation of Fc in a polymeric matrix can improve the dispersion of Fc, increasing the catalyst effect and antibacterial activity of hybrid nanofibers. However, the current reports mainly focus on the preparation and application of various Fc-derivative nanofibers by the electrospinning technology [14–15]. To the best of our knowledge, Fc-PVP composites prepared by electrospinning have not been reported up to now.…”

SummaryNanofibers containing ferrocene (Fc) have been prepared for the first time by electrospinning. In this paper, Fc was dispersed uniformly throughout the poly(vinypyrrolidone) (PVP) matrix for the purpose of combining the properties of PVP and Fc. The effects of solvents and Fc concentration on the morphologies and diameters of nanofibers were investigated. In the DMF/ethanol solvent, the morphologies of the obtained nanofibers significantly changed with the increase of Fc concentration. The results demonstrated that the morphologies of the nanofibers could be controlled through adjusting solvents and Fc concentration. Scanning electron microscopy (SEM) showed that the diameters of the obtained composite fibers were about 30–200 nm at different Fc concentrations. Thermogravimetric analysis (TGA) results confirmed the presence of ferrocene within the PVP nanofibers. X-ray diffraction (XRD) results showed that the crystalline structure of Fc in the fibers was amorphous after the electrospinning process. A biological evaluation of the antimicrobial activity of Fc/PVP nanofibers was carried out by using Gram-negative Escherichia coli (E. coli) as model organisms. The nanofibers fabricated by this method showed obvious antibacterial activity. Electrochemical properties were characterized based on cyclic voltammetry measurements. The CV results showed redox peaks corresponding to the Fc+/Fc couple, which suggested that Fc molecules encapsulated inside PVP nanofibers retian their electrochemical activity. The properties and facile preparation method make the Fc/PVP nanofibers promising for antibacterial and sensing applications.
