    Description / Table of Contents: Trifluoromethylselenyl Compounds of N, P, and AsThe reaction of CF3SeBr with NH3 leads, depending on conditions, to (CF3Se)nNH3-n, where n = 1, 2 or 3. CF3SNCO reacts with CF3SeNH2 to give CF3SNHCONHSeCF3, and (CF3Se)3N with P(C6H5)3 provides CF3SeN =P(C6H5)3. (CF3Se)3E (where E = P, As) is formed by the reaction of Hg(SeCF3)2 with EBr3 in CS2. Analogously, from Hg(SeCF3)2 and P2J4 in CS2 (CF3Se)2PP(SeCF3)2 is obtained that contains (CF3Se)3P as a contamination. While reacting C6H5PJ2 or C6H5P(J)(J)C6H5 with Hg(seCF3)2 respectiverly C6H5P(SeCF3)2 is formed. The latter can be also obtained from (C6H5P)5 and CF3SeSeCF3. IR, 19F, 31P, 77Se NMR, and MS data are given.
    Notes: Umsetzungen von CF3SeBr mit NH3 führen je nach Reaktionsbedingungen zu (CF3Se)nNH3-n (n = 1, 2 und 3). Mit CF3SNCO reagiert CF3SNH2 zu CF3SNH · CO · NHSeCF3; (CF3Se)3N setzt sich mit P(C6H5)3 zu CF3SeN — P(C6H5)3 um. Die Synthese von (CF3Se)3E (E = P, As) erfolgt aus Hg(SeCF3)2 und EBr3 in CS2. Analog erhält man aus Hg(SeCF3)2 und P2J4 in CS2 ein (CF3Se)2PP(SeCF3)2, das mit (CF3Se)3P verunreinigt ist. C6H5P(SeCF3)2 entsteht aus C6H5PJ2 bzw. C6H5P(J)(J)C6H5 und Hg(SeCF3)2 oder aber durch Umsetzung von (C6H5P)5 mit CF3SeSeCF3. IR-, 1H-, 19F-, 31P-, 77Se-NMR und Massenspektren werden angegeben.
