Abstract: | The Preparation of Methylthio(trihalogeno)phosphonium Salts ClnBr3?nPSCH3+MF6?(n = 0–3; M = As, Sb) and Hal3PSCH3+SbCl6?(Hal = Br, Cl) The methylthio(trihalogeno) phosphonium salts BrnCl3?nPSCH3+MF6? (n = 0–3; M = As, Sb) are prepared by methylation of the corresponding thiophosphorylhalides BrnCl3?nPS in the system SO2/CH3F/MF5. The hexachloroantimonates Hal3PSCH3+SbCl6?(Hal = Br, Cl) are synthesized by thiomethylation of PBr3 and PCl3 with CH3SCl/SbCl5. All salts are characterized by vibrational and NMR spectroscopy. |
