    Description / Table of Contents: Mono- and Bis(difluorophosphoranyl)ethylene, n-Hexylidene-fluorophosphorane, and a 2,4-Di-n-pentyl-1λ5, 3λ5 -diphospheteBis(diethylamino)phosphanylethylene, 1, is converted by SF4 into bis(diethylamino)difluorophosphoranylethylene, 2. Analogously trans-1,2-bis(diphenylphosphanyl)ethylene, 3, is converted into trans-1,2-bis(difluorodiphenylphoranyl)ethylene, 4. 2 reacts with n-butyllithium to give n-hexylidene-bis(diethylamino)fluorophosphorane, 5. With more n-butyllithium, the main product n-hexylidene-bis(diethylamino)-n-butylphosphorane, 7, and the by-product 2,4-di-n-pentyl-1,1,3,3-tetrakis(diethylamino)-1λ5, 3λ5 -diphosphete, 8, are formed. With t-butyllithium 2 yields 3,3-dimethyl-butylidene-bis(diethylamino)fluorophosphorane, 6. All new compounds 1, 2, 4-8 are characterized by their nmr and ir spectra.
    Notes: Bis(diethylamino)phosphanylethylen, 1, wird durch SF4 in Bis(diethylamino)difluorphosphoranylethylen, 2, übergeführt. Auf analoge Weise entsteht aus trans-1,2-Bis(diphenylphosphanyl)ethylen, 4. 2 reagiert mit n-Butyllithium zu n-Hexyliden-bis(diethylamino)fluorphosphoran, 5, aus dem mit weiterem n-Butyllithium als Hauptprodukt n-Hexyliden-bis(diethylamino)-n-butylphosphoran, 7, und als Nebenprodukt 2,4-Di-n-pentyl-1,1,3,3-tetrakis(diethylamino)-1λ5, 3λ5-diphosphet, 8, entsteht. Mit t-Butyllithium bildet 2 3,3-Dimethyl-butyliden-bis(diethylamino)fluorphosphoran, 6. Alle neuen Verbindungen 1, 2, 4-8 werden durch ihre NMR- und IR-Spektren charakterisiert.
