چکیده
Selective sulfoxidation of BEDT-TTF (bis(ethylenedithio)-tetrathiafulvalene) with enantiopure (camphoryl-sulfonyl)oxaziridine derivatives provided the inner monosulfoxide, as demonstrated using single crystal X-ray analysis, with an enantiomeric excess of 44% (up to 74% after recrystallization).

Bis(vinylenedithio)tetrathiafulvalene analogues of BEDT-TTF
This review aims to give an overview of the current status of our research on the synthesis of π-electron donor bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF, ET) analogues prepared from 1,8-diketones via a ring forming reaction. The new synthesized π-electron donors have vinyl moieties producing extended π-electron delocalization over the substituent phenyl rings at the peripheries.

Electrocrystallization of bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) in the presence of the tris(chloranilato)ferrate(III) [Fe(Cl2An)3](3-) paramagnetic chiral anion in different stoichiometric ratios and solvent mixtures afforded three different hybrid systems formulated as [BEDT-TTF]3[Fe(Cl2An)3]·3CH2Cl2·H2O (1), δ-[BEDT-TTF]5[Fe(Cl2An)3]·4H2O (2), and α‴-[BEDT-TTF]18[Fe(Cl2An)3]3·3CH2C...

متن کاملElectrical transport in the organic superconductor /1-(BEDT -TTFhAuI2 [with BEDT-TTF bis(ethylenedithio)tetrathiafulvalene]: Influence of x-ray-induced defects on the normal phase and superconducting ground state
We have measured the in-plane and out-of-plane resistivities of the organic superconductor p-(BEDTTTF)zAuIz with disorder introduced by x-ray irradiation. [Here BEDT-TTF is bis(ethylenedithio)tetrathiafulvalene]. For defect concentrations less than 0.15% per mole, Matthiessen's rule is obeyed at all temperatures and a T Z term in the resistivity is found in the temperature region between 5 and ...
متن کاملSynthesis of bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) derivatives functionalised with two, four or eight hydroxyl groups.
Short synthetic routes to a range of BEDT-TTF derivatives functionalised with two, four or eight hydroxyl groups are reported, of interest because of their potential for introducing hydrogen bonding between donor and anion into their radical cation salts. The cycloaddition of 1,3-dithiole-2,4,5-trithione with alkenes to construct 5,6-dihydro-1,3-dithiolo[4,5-b]1,4-dithiin-2-thiones is a key ste...
