Difference in reactivity of triel halides EX3 towards ferrocene

Ionic Liquids of Cationic Sandwich Complexes

“…Arene–ferrocenium ILs were obtained as reddish–orange liquids. They were prepared by the metathesis of ferrocene or substituted ferrocenes with alkylbenzene in the presence of AlCl 3 ,23 followed by anion exchange (Scheme ). Although these salts were stable towards air and water, they were photosensitive and were handled under a red lamp.…”

“…Preparation of arene–ferrocenium salts : Arene–ferrocenium salts 14 a – 19 a and 17 f – 19 f were prepared by metathesis reactions under a nitrogen atmosphere 23. [Fe (C 5 H 5 )(C 6 H 5 Et)][Tf 2 N] ( 18 a ) was prepared by a ligand‐metathesis reaction and an anion‐exchange reaction as follows: A mixture of ferrocene (300.8 mg, 1.613 mmol), AlCl 3 (430.2 mg, 3.226 mmol), and ethylbenzene (10 mL) was heated at 100 °C for 1 h, after which aluminum powder (40.0 mg, 1.481 mmol) was added to the mixture.…”

Synthesis of a Neutral Mixed‐Valence Diferrocenyl Carborane for Molecular Quantum‐Dot Cellular Automata Applications

“…[14] In comparison, Fc + FcC 2 B 9 À (3a)h as one mean Fe À Cl ength of 2.050(2) a nd as econd longer mean length of 2.095 (2) . [15][16][17][18] TheC ÀCb ond lengths within the cages shorten significantly on moving from the closo to the nido structures. These elongated FeÀCb onds are consistent with the formation of localized ferrocenium Fe III centers in Fc + FcC 2 B 9 À (3a)a nd Fc + C 2 B 9 À (3b).…”

Solid State Structure of Bis[(bromo)(dicyclopentadienyl)vanadium(μ2-fluoro)][(bromo)(cyclopentadienyl)vanadium][tetrafluoroborate]

“…0.202 g of V(C 5 H 5 ) 2 Br [11] was dissolved in 20 mL of methylene chloride in a 100mL Schlenk flask. 0.211g of [Fe(C 5 H 5 ) 2 + ]BF 4 − [12] was then added, leading to a brownish-yellow solution. After the solution was allowed to stir for several hours, the solvent was removed in vacuo, and the residue was washed with hexane to remove ferrocene, leaving a greenish colored solid.…”
