Trifluoromethylated 2,3-dihydro-1,3,4-thiadiazoles via the regioselective [3+2]-cycloadditions of fluorinated nitrile imines with aryl, hetaryl, and ferrocenyl thioketones

, p. 147 - 154 (2016)
A series of hydrazonoyl bromides prepared from readily available N-arylhydrazones of fluoral was used for the in situ generation of fluorinated nitrile imines. These 1,3-dipoles were efficiently trapped with aryl and hetaryl thioketones yielding fluoromet

A base-promoted, efficient [3 + 2] annulation between azaoxyallyl cations and thiocarbonyls is reported for flexible access to highly functionalized thiazolidin-4-one derivatives in good to excellent yields. An intriguing feature of this method is the met
Microwave-assisted reactions of α-diazoketones with hetaryl and ferrocenyl thioketones*

, p. 47 - 63 (2017/09/06)
Differently substituted hetaryl thioketones react with less reactive diazoketones under microwave (MW) irradiation in toluene solution. After only 2 min, the reactions were complete and, depending on the type of the used diazoketone, α,β-unsaturated keton
Thia-Diels–Alder reactions of hetaryl thioketones with nonactivated 1,3-dienes leading to 3,6-dihydro-2H-pyrans: evidence for a diradical mechanism
Mlostoń, Grzegorz,Grzelak, Paulina,Linden, Anthony,Heimgartner, Heinz
, p. 518 - 525 (2017/08/30)
[Figure not available: see fulltext.] Dihetaryl thioketones possessing thiophen-2-yl and selenophen-2-yl rings react as “superdienophilic” reagents with nonactivated 1,3-dienes such as 2,3-dimethylbuta-1,3-diene, cyclopentadiene, and mixtures of isomeric
Hetaryl thioketones: Synthesis and selected reactions
Mlosto, Grzegorz,Urbaniak, Katarzyna,Gbicki, Krzysztof,Grzelak, Paulina,Heimgartner, Heinz
, p. 548 - 555 (2015/01/16)
A series of phenyl/hetaryl and bishetaryl thioketones have been prepared via oxygen/sulfur exchange of the corresponding ketones by treatment with Lawesson's reagent. The nonsymmetrical ketones were conveniently accessible via the reactions of lithiated f
RMN 13C de thiocetones - role du groupement thiocarbonyle
Mieloszynski, J. L.,Andrieu, C. G.,Schneider, M.,Paquer, D.
, p. 9 - 15 (2007/10/02)
The shielding effects of the sulfur atom on neighbouring carbons in 36 thioketones have been characterized by 13C NMR.The results are compared with those for the carbonyl derivatives.The importance of these data for structural elucidations is discussed.
