Die HgF₂‐assistierte Addition der CF₃S‐Gruppe an die CN‐Dreifachbindung

Abstract

CF3SCl wird in Gegenwart von HgF2 an die CN‐Dreifachbindung von ClCN addiert unter Bildung von (CF3S)2NCF3 (9). Aus CF3SCl und CF3CN bzw. CCl3CN entstehen die Mono‐Additionsprodukte CF3CFNSCF3 (6) bzw. CF3CFNSCF3 (12) in hohen Ausbeuten. 6 und 12 werden unter milden Bedingungen durch HgF2/X2 (X = Cl, Br) zu den Schwefel(IV)‐Derivaten C2F5NS(F)CF3 (7) bzw. CCl3CF2NS(F)CF3 (17) oxidiert.

2‐Benzothiazolyl‐N‐(arenesulfonyl)‐sulfinimidoyl fluorides

“…Sulfinimidoyl fluorides are practically unexplored compounds that, apparently, are connected with the absence of convenient methods of their preparation. The known syntheses of sulfinimidoyl fluorides are based on the use of remote and toxic reagents: perfluoroalkens [8], thiazyl fluoride [9], fluorine [10][11][12], trifluoromethylsulfur trifluoride [12][13][14] and these methods result only in perfluorosulfinimidoyl fluorides.…”

Sulfur‐containing derivatives of 1,4‐naphthoquinone, part 2: Sulfenyl derivative synthesis

“…Further, sulfenylchlorides and sulfenamides are used in macromolecular chemistry as monomers [1], in the production of such widely known biologically active preparations such as phtalan, captan [2,3], euparen, euparen-M [4,5], as well as in the production of pharmaceutical preparations [3,8], and vulcanizing agents [9,[10][11][12][13][14], what makes their perspective clear in the practical sense.…”

Sulfennaphthoquinones

“…They are used as synthons in preparations of such pharmaceutical preparations as phtalan, captan [1,2], euparen, euparenM [3,4] and vulcanizing agents [5][6][7][8][9][10]. Besides, the derivatives of 1,4-naphthoquinone have revealed themselves as bacteriostatic, antiviral and fungistatic activity substances.…”
