Abstract
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 fuhrt zur Saure (HO)2P(O)CH2SO2OH, von der Ester und Amide dargestellt werden. Die Ester werden in einer Horner-Wittig-Reaktion in α,β-ungesattigte Sulfonsaureverbindungen umgewandelt. Reactions of (Dichlorophosphinyl)methanesulfonyl Chloride Substitution 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.
