    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.

    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.

    Description / Table of Contents: Phenylethinyl-[1,3,2]dithiaphospholane. Bis(dithiaphospholanyl)-[1,4]dithianeNucleophilic substitution of the amino group but no cycloaddition occurs in the reaction of phenyl phenylethinyl phosphinous acid diethylamide, 5, with 2-aminothiophenol forming compound 6. By analogous reaction, phenylethinyl phosphonic bis(diethylamide), 7, and ethane-1,2-dithiol form compound 8. Cycloaddition besides nucleophilic substitution is observed, however, when acetylene bis(phosphonic diethyl-amide), 9, and ethane-1,2-dithiol are reacted resulting in compound 11. All new products are characterized by their nmr, mass, and i.r. spectra. Furthermore, the results of an X-ray structure analysis of 11 are reported.
    Notes: Bei der Reaktion von Phenyl-phenylethinyl-phosphinigsäure-diethylamid, 5, mit 2-Aminothiophenol findet keine Cycloaddition statt sondern eine nukleophile Substitution der Aminogruppe, die zu Verbindung 6 führt. Analog reagiert Phenylethinyl-phosphonigsäure-bis(diethylamid), 7, mit Ethan-1,2-dithiol zu Verbindung 8. Cycloaddition und nukleophile Substitution werden jedoch bei der Umsetzung von Acetylen-bis(phosphonigsäurediethylamid), 9, und Ethan-1,2-dithiol beobachtet; es entsteht Verbindung 11. Alle neuen Reaktions-produkte sind durch ihre NMR-, Massen- und IR-Spektren charakterisiert. Von 11 wird eine Kristallstrukturanalyse mitgeteilt.
