Synthesis and Nuclear Magnetic Resonance Spectroscopic Studies of Alkylene / Alkylidenebis(phosphonic Dihalides) and -bis(fluorophosphoranes)

Chlorine-fluorine exchange in the bis(phosphonic dichlorides) Cl2P(O)-X-P(O)Cl2 (1a - c) with AsF3 furnishes the bis(phosphonic difluorides) F2P(O)-X-P(O)F2 (2a - c).Reaction of 2a - c with SF4 leads to bis(tetrafluorophosphoranes) F4P-X-PF4 (3a - c) (X = CH2, CH2CH2, trans-CH=CH).Additional methods of synthesis are indicated for compound 3a (X = CH2) which are based on the cleavage of the Si-C bond with PF5 in the Si-C bonded precursors 2 and Me3SiCH2PF4.The NMR spectra of compounds 2 and 3 are discussed.
