    Description / Table of Contents: Extremely Reactive C=C-Double Bonds, IV1). Unusual Reactions with Thiophenol, 1,2-Ethanedithiol, and other Sulfur CompoundsReactions of thiophenol and 1,2-ethanedithiol with imidazolidine derivatives leads to solvolysis with opening or conversion of the imidazolidine system [eq. (7), (9), or (10)] as well as to hydrogenation, partly without a change in the ring system [eq. (2), (5), (6), (9), or (11)]. Benzophenone diaryl dithioacetals are reduced to aryl benzhydryl sulfides by thiophenol [eq. (8)]. 1,1′,3,3′-Tetraphenyl-Δ2,2′-biimidazolidine (9) desulfurates thioacetic acid, bibenzoyl disulfide, and dixanthogen [eq. (13)].
    Notes: Thiophenol und 1,2-Ethandithiol reagieren mit Imidazolidin-Derivaten sowohl solvolytisch unter Ringöffnung oder -umwandlung [vgl. Gl. (7), (9) oder (10)] als auch teilweise bei Erhaltung des Imidazolidin-Ringes, unter Hydrierung [vgl. Gl. (2), (5), (6), (9) oder (11)]. Diaryldithioacetale des Benzophenons werden durch Thiophenol zu Aryl-benzhydryl-sulfiden reduziert [vgl. Gl. (8)]. 1,1′,3,3′-Tetraphenyl-Δ2,2′-biimidazolidin (9) wirkt entschwefelnd auf Thioessigsäure, Dibenzoyldisulfid und Dixanthogen [vgl. Gl. (13)].
