  摘要：

  The reaction of phenyldifluorophosphine 1 with calcium hydroxide is an alternative route to form phenylphosphonous acid fluoride 2. The reaction of 2 with methyl ketones, MeC(:O)R, leads to addition products of type PhP(:O) (F)C(Me) (R)OH.A single crystal X-ray structure determination is described for the adduct PhP(:O) (F)C(CH3)(2)OH 8 obtained from phenylphosphonous acid fluoride 2 and acetone; hydrogen bonds of the form O-H ... O=P are observed. (C) 1997 Elsevier Science S.A.

  A series of novel push–push I and push–pull II carbene-stabilized complexes of phosphorus(V) fluorides bearing substituents with liquid-crystalline properties were synthesized by the oxidative addition of difluoroamines to phosphorus(III) halides. These octahedral complexes were characterized by NMR spectroscopy and X-ray analysis.

  Ph2P-PF2Ph2 has been identified by means 19F- and 31P- NMR spectroscopy as an intermediate product of the disproportionation of Ph2PF. The disproportionation is catalyzed by acids. The reaction mechanism is discussed. PhPF2 disproportionates faster in solution in acetonitrile than neat, forming (PhP)6, instead of (PhP)5.

  The organophosphonous-N-(N′,N′,N″,N″-tetramethyl)guanidinide fluorides RP(F)N=C(NMe₂)₂ 2a (R = t-Bu) and 2b (R = Ph) were synthesized. They are readily oxidized by the urea-H₂O₂ 1:1 adduct and by elemental sulfur, selenium and tellurium to give the compounds 4a/b, 5a/b, 6a/b and 7a/b respectively. Compound 2b undergoes a Staudinger reaction with triphenylmethyl azide to yield the phosphine imide 3. The compounds were characterized by ¹H-, ¹³C-, ¹⁹F and ³¹P NMR spectroscopy, and 6a/b and 7a/b by ⁷⁷Se and ¹²⁵Te NMR spectroscopy. The structures of the sulfur compound 5b and the selenium compound 6a were confirmed by X-ray crystal structure analysis. Both molecules exhibit short P-N-bonds [158.9(2) pm and 159.8(3) pm] consistent with partial double bond character even though the P(:S) and the P(:Se) bonds are not longer than a normal double bond.
