Abstract

Trifluorom ethylselenylthiocarbonyls form with CF3-nClnSCl or CF3SeCl the corresponding disulfanes or selanesulfanes. Oxidation of CF3SeC(S)X , X = CF3Se, CF3S, Cl, or Br, with 3-Cl - C6H4C(O)OOH yields com pounds CF3Se(X )C = S = O . Only decomposition products are obtained from (CF3Se)2CSe and Cl2, CF3SeCl, CF3SCl, or 3-Cl-C6H4C(O)OOH . The preparation o f com pounds RN = Se = NR , R = (CH3)3Si, CF3C(O), or CF3SO2, is described. Physical and spectroscopical data of the new substances are provided
