    Description / Table of Contents: Sulfur Diimides Containing Organoelement Substituents of Main Group 5A suspension of the salt K2SN2 (1) in acetonitrile reacts with diorgano-element halides R2EX (E = P, As, Sb, Bi; X = Cl or Br) at -40 °C to give new sulfur diimides, S(N - Er2)2. The arsino derivative 3b is the most stable member of the series of tert-butyl compounds, S(N - EtBu2)2 (E = P (2b), As (3b), Sb (4b), and Bi (5b)), while 5b decomposes under ambient conditions. The arsino derivatives S(N - AsR2)2 with R = methyl (3a), cyclohexyl (3c), and phenyl (3d) have also been prepared. The IR-, NMR-, and mass spectra are discussed.
    Notes: Das Salz K2SN2 (1) reagiert in Acetonitril-Suspension bei - 40 °C mit Diorganylelementhalogeniden R2EX (E = P, As, Sb, Bi; X = Cl oder Br) zu neuen Schwefeldiimiden S(N - ER2)2. In der Reihe der tert-Butylverbindungen S(N - EtBu2)2 (E = P (2b), As (3b), Sb (4b) und Bi (5b) und Bi (5b) ist 3b am beständigsten; 5b zersetzt sich unter Normalbedingungen. Weiterhin wurden die Arsenderivate S(N - AsR2)2 mit R = Methyl (3a), Cyclohexyl (3c) und Phenyl (3d) dargestellt. Die IR-, NMR- und Massenspektren werden diskutiert.
