R. Minkwitz et B. Back, PREPARATION AND SPECTROSCOPIC CHARACTERIZ ATION OF THE TRIHALOGENOPHOSPHONIUM SALTS PHAL(3)X(- (HAL=CL,BR X=H,D M=AS,SB)()MF(6)), Zeitschrift fur Naturforschung. B, A journal of chemical sciences, 49(2), 1994, pp. 221-224
PHal(3)X(+)MF(6)(-) (Hal = Cl, Br; X = H, D; M = As, Sb) are prepared
at 213 K by protonation of the phosphortrihalides in the superacidic m
edia XF/MF(5). The salts are characterized by P-31, MS, IR and Raman s
pectroscopy.
