Description
Summary:Tin element compounds R 3SnE (R = Me or Ph; E = Net 2, OMe or OSnMe 3) react with R 2N−P = NR (R = SiMe 3) ( 1) by 1,1-addition at phosphorus yielding the P-stannylated iminophosphoranes R 3Sn(E)P(NR)NR 2 ( 2–6). In the 1,1-addition reaction of the cyclodistannazane ( 1Bu 2SnNMe) 2 with 1 the five-membered stanna heterocycle 1 Bu 2 Sn P[(NR)(NMeR)]N(Me)Sn tBu 2) NR ( 7) is formed by ring expansion. The constitution of the novel compounds was characterized by NMR spectroscopy ( 1H, 31P, 119Sn), and for the triphenylstannyl compound Ph 3Sn(Et 2N)P(=NR)NR 2 ( 3) further by an X-ray structure analysis (space group P2 1/ c; Z = 4). Zinn-Elementverbindungen R 3SnE (R = Me oder Ph; E = Net 2, OMe oder OSnMe 3) reagieren mit (R 2N−P = NR (R = SiMe 3) ( 1]) unter 1,1-Addition am Phosphor zu P-stannylierten Iminophosphoranen R 3Sn(E)P(NR)NR 2 ( 2–6). Die 1,1-Addition des Cyclodistanazan ( 1Bu 2SnNMe) 2 an 1 erfolgt unter Ringexpansion und Bildung des fünfgliedrigen Stannaheterocyclus 1 Bu 2 Sn P[(NR)(NMeR)]N(ME)Sn( tBu 2) NR ( 7). Die Konstitution der neuen Verbidungen wurde durch NMR-Spketroskopie ( 1H, 31P, 119Sn), und Molekülstruktur des Triphenylstannyl-Derivats Ph 3SnP(NEt 2)(=NR)NR 2 ( 3) zusätzlich durech eine Röntgenstrukturanalyse charakterisiert (Raumgruppe P2 1/ c; Z = 4).
