Studien über elektronegativ substituierte Thiocarbonylverbindungen, 3: Reaktionen der Trithiocarbonat‐ S , S ‐dioxide mit Elektrophilen und 1,3‐Dipolen

Abstract: Trithiocarbonat‐S,S‐dioxide 1 reagieren glatt mit Chlor zu den entsprechenden α‐Chlorsulfenyl‐chloriden 2. Diese liefern mit Thiolen die Disulfide 3, mit Sulfinsäuren die S‐Thiosulfonate 4 und mit sekundären Aminen die Sulfenamide 5. Die Sulfenylchloride 2 reagieren mit tert‐Butylamin zu den Thiocarbonyl‐S‐imiden 6, dem ersten Beispiel für Thiocarbonyl‐S‐imide ohne Delokalisierung der negativen Ladung des Stickstoffatoms durch einen mesomeriefähigen N‐Substituenten. Die Imide 6 addieren Phenyllithium zu den Su… Show more

“…In this case, subsequent HCl elimination of the adducts 8 to give sulfinimides 9 (thiocarbonyl S-imides) should be possible (Scheme 3) [6 -9]. These and related ylides are important building blocks for cycloadditions and other reactions [8] [10], including conversions with amines [11], alkenes [12] [13], and metal-organic compounds such as PhLi [14] or RMgBr [15]. In general, sulfinimides are reactive intermediates, which easily undergo further reactions.…”

“…The corresponding reaction of C-sulfonyldithioformates 54 leads to R 1 SO 2 (R 2 S)CClSCl 55 [54,55]. The latter can, depending on the substitution pattern and the reaction conditions, rearrange to the disulfide R 1 SO 2 CCl 2 SSR 2 56 or to the thiosulfonate R 1 SO 2 SCCl 2 SR 2 57 [56].…”

“…In the second case the co-product was dibenzoyl trisulfide, [15] in the third case diphenyl disulfide. [16] Substitution/Reduction of 2. a) With p-Toluenesulfinate Ions: A general procedure [17] was followed. A two-phase mixture of sodium ptoluenesulfinate dihydrate (2.20 g, 10 mmol), 2 (10 mmol), tetrabutylammonium hydrogen sulfate (0.20 g), 25 mL water, and 25 mL benzene was stirred at room temperature until TLC showed that the reaction was complete (5 h).…”
