57Fe Mössbauer spectroscopic studies on M(CO)5(azaferrocene) complexes (M = Cr, Mo, W). The crystal structures of W(CO)5(azaferrocene) and W(CO)5(2,5-dimethylazaferrocene)

The synthesis and characterisation of 1′-ethynyl-2,5-dimethylazaferrocene and derivatives

“…Cyclic voltammograms of 1, 2 and 6 in CH 2 Cl 2 with 0.1 M Bu 4 NClO 4 on Pt vs. 5 + /5, scan rate: 0.1 V s À1 .nitrogen of the aza-ferrocenyl moiety is very similar to those seen previously in related structures [16b,17,26]. The tungsten centre has a distorted octahedral geometry with cis angles in the range 86.42(9)-93.52(7)°, and trans angles between 174.36(9)°and 179.20(7)°(Table 2).…”

The synthesis, structure, electrochemistry and in vitro anticancer activity studies of ferrocenyl-thymine conjugates

“…Microanalyses were determined by Analytical Services of the Polish Academy of the Sciences (qód z). 2,5-dimethylazaferrocene [55], W(CO) 5 -2,5-dimethylazaferrocene [56] were prepared according to the literature procedures. Electrochemical work was performed on a Princeton Applied Research VersaStat3 potentiostat in a homebuilt vacuum tight one-compartment cell using Pt electrodes as the working electrode, a platinum spiral as the counter electrode and a silver spiral as a pseudo-reference electrode.…”

Azaferrocene‐Based PNP‐Type Pincer Ligand: Synthesis of Molybdenum, Chromium, and Iron Complexes and Reactivity toward Nitrogen Fixation

“…Azaferrocenes are typically redox‐active compounds and have unique electronic properties . Azaferrocenes are known to work as strong σ‐donating and poor π‐accepting ligands to transition‐metal complexes . More recently, optically active azaferrocene derivatives were used as organocatalysts and chiral ligands in various asymmetric reactions .…”
