Darstellung und spektroskopische Charakterisierung der Trihalogenphosphonium-Salze PHal3X+MF6- (Hal = Cl, Br; X = H, D; M = As, Sb) / Preparation and Spectroscopic Characterization of the Trihalogenophosphonium Salts PHal3X+MF6- (Hal = Cl, Br; X = H, D; M = As, Sb)

Abstract

PHal3X+MF6- (Hal = Cl, Br; X = H, D; M = As, Sb) are prepared at 213 K by protonation of the phosphortrihalides in the superacidic media XF/MF5. The salts are characterized by 31P, MS, IR and Raman spectroscopy.
