Preparation and Structures of Crystalline Aromatic Cation-Radical Salts. Triethyloxonium Hexachloroantimonate as a Novel (One-Electron) Oxidant.
نویسندگان
چکیده
Triethyloxonium hexachloroantimonate [Et(3)O(+)SbCl(6)(-)] is a selective oxidant of aromatic donors (ArH), and it allows the facile preparation and isolation of crystalline paramagnetic salts [ArH(+)(*), SbCl(6)(-)] for the X-ray structure determination of various aromatic cation radicals. The mechanistic relationship between the Meerwein salt [Et(3)O(+)SbCl(6)(-)] and the pure Lewis acid oxidant SbCl(5) is based on a prior ethyl transfer from oxygen to chlorine within the ion pair.

Disproportionation and Structural Changes of Tetraarylethylene Donors upon Successive Oxidation to Cation Radicals and to Dications
The stepwise (one-electron) chemical oxidation of the tetraphenylethylene donor and its substituted analogues (D) can be carried out by electron exchange with aromatic cations or antimony(V) oxidants to selectively afford the cation radical (D+•) initially and then the dication (D2+). The ready interchange of the latter establishes the facile disproportionation (i.e., 2D+• h D2+ + D) that was o...

[structure: see text]. Macromolecules 1c and 2c bearing multiple redox-active sites are synthesized by an efficient palladium-catalyzed coupling of 2,5-dimethoxytolylmagnesium bromide with readily available hexakis(4-bromophenyl)benzene and tetrakis(4-bromophenyl)methane. These macromolecular electron donors undergo reversible oxidation at a constant potential of 1.15 V vs SCE to yield robust, ...
متن کاملApplications of Ferrocenium Salts in Organic Synthesis
Abstract Ferrocenium salts can be easily obtained from ferrocene by either synthetic preparation or in situ reaction. The ferrocenium ion can act as a one-electron oxidant and thus initiate or promote a range of radical processes. Ferrocene itself can donate electrons to suitable substrates, resulting in useful transformations. Ferrocenium salts can also act as mild Lewis acids. This paper high...

A new, efficient and mild approach for the oxidative dehydrogenation of dihydropyrimidinones and thiocyanation of aromatic compounds using 1,1,2,2-tetrahydroperoxy-1,2-diphenylethane (THPDPE) as a terminal oxidant was developed. Initially, various substrates bearing different electron-donating and electron-releasing functionalities were synthesized and next under the optimized reaction conditio...

Sterically hindered olefins are efficiently reduced to the corresponding alkanes by the boranemethyl sulfide (BMS) complex at room temperature (or below) in dichloromethane containing a mild one-electron oxidant (such as an aromatic cation radical) or by the passage of an anodic current. In an alternative procedure, the hydrogenation of the same (electron-rich) olefins with the BMS complex (in ...
