    Description / Table of Contents: Synthesis and NMR Spectroscopic Studies of Phosphorus Compounds with Vinyl and Ethinyl GroupsThe synthesis of a series of phosphorus compounds of types CH2 = CHPX2 (X = Hal) and CH2 = CHP(Y)X2 (Y = O, S: X = Hal, OEt) as well as of CH2 = CHPF4. HC ≡ CP(O)F2, and HC ≡ CPF4 is described. Characterization of the new compounds was, especially, by NMR spectroscopy (1H, 13C, 31P. 19F). The 13C NMR spectra were investigated with regard to a correlation between J(CP) and the s-character of the carbon-phosphorus bond.
    Notes: Die Synthesen einer Reihe von Phosphorverbindungen der Typen CH2= CHPX2 (X = Hal) und CH2 = CHP(Y)X2(Y = O, S; X = Hal, OEt) sowie von CH2 = CHPF4, HC ≡ CP(O)F2 und HC ≡ CPF4 werden beschrieben. Die Charakterisierung der neuen Verbindungen erfolgte vor allem durch NMR-Spektroskopie (1H, 13C, 31P, 19F). Die 13C-NMR-Spektren wurden, unter Heranziehung von weiteren Daten aus der Literatur, in bezug auf den Zusammenhang zwischen J(CP) und dem s-Charakter der Kohlenstoff-Phosphor-Bindung untersucht.

    Description / Table of Contents: Reactions of (Dichlorophosphinyl)methanesulfonyl ChlorideSubstitution of chlorine by fluorine in (dichlorophosphinyl)methanesulfonyl chloride (2) Cl2P(O)CH2SO2Cl leads to the fluorides F2P(O)CH2SO2X (X = Cl, F); their reactions leading to the fluorophosphorane F4PCH2SO2F and fluorophosphate anions of the type [F5PCH2SO2X]- and [O(F)P(O)CH2SO2X]- (X = Cl, F) were investigated. Hydrolysis of 2 yields the acid (HO)2P(O)CH2SO2OH, from which esters and amides have been derived. The conversion of the esters to α,β-unsaturated sulfonic acid derivatives via the Horner-Wittig reaction is also described.
    Notes: Substitution von Chlor durch Fluor in (Dichlorphosphinyl)methansulfonylchlorid (2), Cl2P(O)CH2SO2Cl liefert die Fluoride F2P(O)CH2SO2X (X = Cl, F), deren Umwandlung zum Fluorphosphoran F4PCH2SO2F und zu Fluorophosphat-Anionen des Typs [F5PCH2SO2X]- bzw. [O(F)P(O)CH2SO2X]- (X = Cl, F) untersucht wird. Die Hydrolyse von 2 führt zur Säure (HO)2P(O)CH2SO2OH, von der Ester und Amide dargestellt werden. Die Ester werden in einer Horner-Wittig-Reaktion in α,β-ungesättigte Sulfonsäureverbindungen umgewandelt.
