The nucleophilic trifluoromethylation of dithioesters bearing a nucleofugal group in α-position, using CF3TMS under fluoride activation, afforded unprecedented S-CF3 ketene dithioacetals via a domino process thiophilic trifluoromethylation–β-elimination. The best results were obtained with non-enolisable α-carbamoyloxydithioesters. The higher homologues S-C2F5 ketene dithioacetals were prepared by
在氟化物活化下使用CF 3 TMS ,在α位置带有一个核褐藻基的二硫代酯的亲核三氟甲基化,通过多米诺过程的亲硫三氟甲基化-β-消除作用,提供了前所未有的S -CF 3烯酮二硫缩醛。用不可烯醇化的α-氨基甲酰氧基二硫代酯可获得最佳结果。较高的同系物S -C 2 F 5烯酮二硫缩醛通过类似的方法制备。这些新的二硫缩醛在硫磺上与甲基化试剂发生定量和化学选择性反应,生成稳定的二甲基s型盐。它们更典型地与三氟甲磺酸反应,在β-碳上发生质子化反应,生成二硫鎓盐,其特征在于溶液,但不可分离。

Thianthrene derivative of the Formula (I): wherein R1 to R8 may be the same or different and are selected from hydrogen, Cl, F, a partially or fully fluorinated C1 to C6 alkyl group, and wherein n is 0 or 1, with the proviso that at least one of R1 to R8 is not hydrogen and process for C-H functionalization of aromatic compounds using this compound.
A highly stereoselective synthesis of fluorinated 1,3-disubstituted isoindolines is described. To this end, a tandem reaction consisting of a diastereoselective addition of fluorinated nucleophiles to Ellman’s N-(tert-butanesulfinyl)imines followed by an intramolecular aza-Michael reaction has been developed. This strategy allows for the construction of isoindolines bearing several degrees of fluorination
