Synthesis of bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) derivatives functionalised with two, four or eight hydroxyl groups [PDF]

, 2007
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.

Synthesis of 3-(4-(Benzo[d]thiazol-2-yl)phenyl)-5-aryl-1,3,5-oxadiazinane-4-thiones and 1-(4-(Benzo[d]thiazol-2-yl)phenyl)-5-methyl-3-aryl-1,3,5-triazinane-2-thiones

SynOpen, 2018
In this investigation 4-(benzo[d]thiazol-2-yl)benzenamine was reacted with aryl isothiocyanates to give 1-(4-(benzo[d]thiazol-2-yl)phenyl)-3-aryl thioureas 2, which were cyclized with acid to afford 3-(4-(benzo[d]thiazol-2-yl)phenyl)-5-aryl-1,3,5 ...

Photochemical Transformations of Tetrazole Derivatives: Applications in Organic Synthesis [PDF]

, 2010
Tetrazoles remain a challenge to photochemists. Photolysis leads to cleavage of the tetrazolyl ring, may involve various photodegradation pathways and may produce a diversity of photoproducts, depending on the structure and conformational flexibility of

Synthetic strategies for preparing BEDT-TTF derivatives functionalised with metal ion binding groups [PDF]

, 2006
The syntheses of BEDT-TTF (ET) derivatives with potential metal ion binding pyridyl, bipyridyl and terpyridyl groups are achieved either by stepwise construction of the organosulfur core or via reactions of hydroxymethyl-ET for which a cheap and ...

6-Methylpyridine-2(1H)-thione [PDF]

Acta Crystallographica Section E Structure Reports Online, 2010
There are two unique mol-ecules in the asymmetric unit of the title pyridine-thione derivative, C(6)H(7)NS, each of which adopts the thione rather than the mercaptan form. The rings in both mol-ecules are essentially planar, with maximum deviations from the least-squares planes through all non-H atoms of 0.021 (2) and 0.017 (2) Å.

NHC in Imidazolium Acetate Ionic Liquids: Actual or Potential Presence? [PDF]

, 2018
Ionic liquids (ILs) are considered in the majority of cases green solvents, due to their virtually null vapor pressure and to the easiness in recycling them.

Eine einfache Synthese von 2-Oxazolin-5-onen und verwandten Verbindungen via Amidcyclisierungen

CHIMIA, 1982
Acid catalyzed cyclization of diamides 3 leads to 2-oxazolin-5-ones of type 2 in high yield (Scheme 2). Resolution of racemic oxazolinone 2b is accomplished by reaction with (S)-phenylalanin dimethylamide ((S)-5) to yield a diastereomeric mixture of ...

The genome sequence of Barbarea vulgaris facilitates the study of ecological biochemistry [PDF]

, 2017
peer-reviewedThe genus Barbarea has emerged as a model for evolution and ecology of plant defense compounds, due to its unusual glucosinolate profile and production of saponins, unique to the Brassicaceae. One species, B.
