    Description / Table of Contents: Reactions of λ5-Diphosphetes with COS and CO2. Dihydro-λ5-Phosphetes1,1,3,3-Tetrakis(dimethylamino)-1λ5,3λ5-diphosphete, 1, reacts with COS to yield the (3-oxo-3,4-dihydro-1λ5-phosphete-2-yl)-phosphonothioic bis(dimethylamide) 7. Reaction of dimethyl substituted 1, i.e. 1,1,3,3-tetrakis(dimethylamino)-2,4-dimethyl-1λ5,3λ5-diphosphete 4, with COS and CO2 results in (3-oxo-2,3-dihydro-1λ5-phosphete-2-yl)-phosphonothioic bis(dimethylamide) 9, and (3-oxo-2,3-dihydro-1λ5-phosphete-2-yl)-phosphonic bis(dimethylamide) 10, respectively. Reaction mechanisms are suggested. 7, 9 and 10 are characterized by their properties, and their nmr, mass-, and ir-spectra. The results of X-ray structural analyses of 9 and 10 are reported and discussed.
    Notes: 1,1,3,3-Tetrakis(dimethylamino)-1λ5, 3λ5-diphosphet, 1, reagiert mit COS zu (3-Oxo-3,4-dihydro-1λ5-phosphet-2-yl)-phosphonothiosäure-bis(dimethylamid) 7. Die Umsetzung von dimethylsubstituiertem 1, d. h. 1,1,3,3-Tetrakis(dimethylamino)-2,4-dimethyl-1λ5,3λ5-diphosphet 4 mit COS und CO2 führt zu (3-Oxo-2,3-dihydro-1λ5-phosphet-2-yl)-phosphonothiosäure-bis(dimehthylamid) 9 bzw. (3-Oxo-2,3-dihydro-1λ5-phosphet-2-yl)-phosphonsäure-bis(dimethylamid) 10. Es werden Reaktionsmechanismen vorgeschlagen. 7, 9 und 10 sind durch Eigenschaften und ihre NMR-, Massen- und IR-Spektren charakterisiert. Die Ergebnisse der Röntgenstrukturanalysen von 9 und 10 werden mitgeteilt und diskutiert.
