    Description / Table of Contents: N-Brom-bis(trifluormethyl)-amin, (CF3)2NBr, reagiert mit NO2, NO und CO unter Bildung von (CF3)2NONO, (CO3)2NNO bzw. (CF3)2NCOBr. Das schon beobachtete einheitliche Reaktionsverhalten des (CF3)2NBr gegenüber einfachen ungesättigten Kohlenstoffverbindungen wurde auch bei C2H4, C2H2 sowie C2F4 gefunden, die (CF3)2NC2H4Br. (CF3)2NC2H2Br bzw. (CF3)2NC2F4Br ergeben. Mit AgCN wird CF3N = CF2 gebildet, und die Reaktion mit Ag2CO3 liefert als Hauptprodukt CF3N = NCF3.
    Notes: N-Bromobistrifluoromethylamine, (CF3)2NBr reacts with NO2, NO and CO to yield (CF3)2NONO, (CF3)2NNO and (CF3)2NCOBr, respectively. The reaction of (CF3)2NBr with unsaturated hydrocarbons and fluorocarbons has been confirmed, reaction with C2H4 C2H2 and C2F4 giving (CF3)2NC2H4Br, (CF3)2NC2H2Br and (CF3)2NC2F4Br. Reaction with AgCN yields CF3N = CF2, and that with Ag2CO3, CF3N = NCF3, as the chief product.

    Description / Table of Contents: Reactions of Tetraphosphorus Trichalcogenides with Alkyl IodidesReactions of alkyl iodides RI (R = CHI2, CH2I or tert-Butyl) with P4E3 (E = S or Se) under the influence of light resulted in cleavage of the basal P3 ring. β-P4E3(I)R was formed initially, then it rearranged to the more stable α-P4E3(I)R structure. 31P NMR data of these products were measured and discussed, along with 77Se data for α- and β-P477SeSe2(I)CHI2. On reaction of P4S3 with tert-butyl iodide in CS2 or with sec-butyl iodide or iso-propyl iodide in dioxane, the new type of compounds P5S2R was observed. In this a sulfur bridge of P4S3 is replaced by a P—R group. 31P-NMR data for these compounds are reported.
    Notes: Bei der Reaktion von Alkyliodiden RI (R = CHI2, CH2I und tert-Butyl) mit P4E3 (E = S; Se) in CS2 wird unter Lichteinwirkung eine Bindung des basalen P3-Ring gebrochen. Es bildet sich β-P4E3(I)R, das sich nach einiger Zeit in das stabilere α-P4E3(I)R umwandelt. Die 31P-NMR Daten dieser Verbindungen und zusätzlich die 77Se-Daten für α- und β-P477SeSe2(I)CHI2 wurden gemessen und diskutiert. Bei der Reaktion von P4S3 mit tert-Butyliodid in CS2 bzw. mit sec-Butyliodid oder iso-Propyliodid in Dioxan wird der neue Verbindungstyp P5S2R beobachtet, in dem eine Schwefelbrücke des P4S3 durch eine P—R-Gruppe ersetzt ist, auch seine 31P-NMR-Daten werden wiedergegeben.

    Description / Table of Contents: Bicyclic Iodo-tetrachalcogena-triphospha-heptanesThe compounds P3Se4-nSnI (n = 0, 1, 2) have been identified by 31P nmr spectroscopy. They were prepared by a direct thermal reaction of red phosphorus, sulfur, selenium and iodine in the stoichiometric ratio. These iodides could be converted into corresponding bromides and chlorides by substitution reactions. All molecules show a diselenium bridge in which, in contrast to the other selenium positions, selenium could not be replaced by sulfur. Similar effects were observed for the diselenium bridges of P2Se5. Systematic changes of the chemical shifts and coupling constants are caused by alterations in the molecular geometry, either by replacement of selenium by sulfur, or of iodine by more electronegative ligands. An intramolecular exchange reaction is observed for all molecules.
    Notes: Die Verbindungen P3Se4-nSnI (n = 0, 1, 2) wurden durch 31P-NMR-Spektroskopie als Reaktionsprodukte bei der thermischen Reaktion von rotem Phosphor, Schwefel, Selen und Iod im entsprechenden Verhältnis beobachtet. Über Substitutionsreaktionen konnten diese Iodide in die Bromide und Chloride überführt werden. Alle Moleküle besitzen eine Diselenbrücke, in der das Selen, im Gegensatz zu den anderen Selenpositionen, nicht durch Schwefel ersetzt werden kann. Die gleiche Beobachtung wird auch an den beiden Diselenbrücken des P2Se5 gemacht. Systematische Veränderungen der chemischen Verschiebungen und der Kopplungskonstanten werden durch Verzerrung des Molekülgerüstes beim Ersatz von Selen durch Schwefel oder des Iods durch elektronegativere Liganden hervorgerufen. In allen Molekülen ist ein intramolekularer Austauschprozeß zu beobachten.
