Darstellung, Eigenschaften, KMR-, IR- und Raman-Spektren von Verbindungen des Typs R-P(Se)F₂, R-P(Se)FC1 und R-P(Se)Cl₂ / Preparation, Chemical Properties, NMR- and Vibrational Spectra of Compounds of the Type R-P(Se)F₂-, R-P(Se)FCl and R-P(Se)Cl₂

Abstract

R-P(Se)F 2 - (R = CH 3 , C 2 H 5 , C 3 H 11 , C 6 H 5 , N(CH 3 ) 2 , N(C 2 H 5 ) 2 , NHSi(CH 3 ) 3 ) and R-P(Se)FCl-compounds (R = CH 3 , C 2 H 5 ) can be prepared by reaction of R-P(Se)Cl 2 -derivatives with antimony(III)fluoride under reduced pressure. In some cases the oxidation of fluorophophines with elemental selenium is successful. The isolated compounds are colourless volatile liquids which are sensitive to air and moisture. The chemical properties are described. 1 H-, 19 F-, 31 P-NMR-, IR- and Raman-spectroscopic data are given. Main stretching frequencies are discussed by comparison with similar oxygen- and sulphur-compounds.
