    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.

    Reactions of 1,1,3,3-tetrakis(dimethylamino)-1λ5,3λ5-diphosphete with diphenylchlorophosphane and methyl iodide (1996)

    Notes: 1,1,3,3-Tetrakis(dimethylamino)-1λ5,3λ5-diphosphete, 1, reacts with diphenylchlorophosphane to yield 1,1,3,3-tetrakis(dimethylamino)-4-diphenylphosphanyl-1,2-dihydro-3λ5-[1,3]diphosphetium chloride, 2, or, depending on the reaction conditions, the isomer compound 3. The cation of 2 is deprotonated by LiN[Si(CH3)3]2 to give the diphenylphosphanyl-substituted derivative of 1, i.e., compound 4. Methyl iodide adds to 1 to form 1,1,3,3-tetrakis(dimethylamino)-4-methyl-1,2-dihydro-3λ5-[1,3]diphosphetium iodide, 6. Deprotonation of 6 with n-butyllithium leads to the monomethyl derivative of 1, i.e., compound 7. Physical properties, NMR spectra, and mass spectra of compounds 2-4, 6, and 7 are described. The results of the X-ray structural analysis of 6 are reported and discussed. © 1996 John Wiley & Sons, Inc.

    Notes: The 1,2-azaphosphinine, 9, and the 1,3-diphosphinine, 10, can be isolated from a mixture resulting from the reaction of 1,1,3,3-tetrakis(dimethylamino)-1λ5,3λ5-diphosphete, 1, and ethyl isothiocyanate. The reaction of 1 with phenyl isothiocyanate yields the 1,2-azaphosphinine, 16. Mechanisms for the formation of the compounds 9, 10, and 16 are suggested. The properties, the NMR, mass, and IR spectra, and the molecular and crystal structures of 9 and 10 are described and discussed.
