Zur Reaktion von Trimethylsilyl-difluorophosphat, Trimethylsilyl-dimethylphosphinat und Difluorophosphorsäureanhydrid mit TiCl4 bzw. SbCl5 / On the Reactions of Trimethylsilyl Difluorophosphate, Trimethylsilyl Dimethylphosphinate and Difluorophosphoric Acid Anhydride with TiCl4 and SbCl5, respectively

Abstract

Abstract TiCl4 reacts with trimethylsilyl difluorophosphate (Me3SiPO2F2) and with trimethylsilyl dimethylphosphinate (Me3SiPO2Me2) at room temperature under cleavage of the Si-O bond to give the principal products Cl2Ti(PO2F2)2 and Cl2Ti(PO2Me2)2, respectively. The former product has also been obtained from the reaction of P2O3F4 with TiCl4-SbCl5 is capable of cleaving the P-O bond in P2O3F4 to give Cl4SbPO2F2, but forms addition compounds with Me3SiPO2F2 and Me3SiPO2Me2 in which the terminal oxygen atoms of the esters are bound to antimony. IR spectra have been used to elucidate the structures of the prepared compounds.
