Phosphane-stabilized phosphenium cations react with silanes to effect either reduction to primary or secondary phosphanes, or formation of P-P bonded species depending upon counteranion. This operates for in situ generated phosphenium cations, allowing catalytic reduction of P(III)-Cl bonds in the absence of strong reducing agents. Anion and substituent dependence studies have allowed insight into the competing mechanisms involved.

The first perfluorovinyl alkyl-containing phosphines of the type PR 2(CF=CF2) (R = Et, iPr, Cy) are reported. The reactivity of these air- and moisture-stable materials has been explored, both at the phosphorus centre and at the fluorovinyl moiety. When PR 2(CX=CF2) (X = F, Cl) is reacted with LiAlH4 a mixture of PR2(CX=CFH) isomers and other defluorinated materials are produced, but the reaction with LiAlH(OBut)3 affords the single products Z-PR2(CF=CFH) or E-PR2(CCl=CFH), respectively, in high yields. Reaction of the fluorovinyl alkyl phosphines with hydrogen peroxide, elemental sulfur or selenium yields fluorovinyl-containing phosphine oxides, sulfides and selenides, respectively. The phosphine sulfide SPPr2i(CF=CF2) is the first perfluorovinyl phosphorus(v) compound to be characterised crystallographically and it exhibits an unusually short [1.9358(9) A] P=S bond. Reaction of fluorovinyl phosphines with XeF2 results in compounds of the type F 2PR2(CF=CF2), identified on the basis of multinuclear NMR studies. These compounds decompose in the presence of moisture to yield the respective phosphine oxides. Reaction of OPPh2(CF= CF2) with Br2 results in bromine addition across the double bond to give OPPh2(CFBrCF2Br).
DARSTELLUNG UND NMR-SPEKTROSKOPISCHE CHARAKTERISIERUNG EINIGER DI-n-ALKYL- UND n-ALKYLARYL-CHLOROPHOSPHANE

A series of di-n-alkyl and n-alkylaryl chlorophosphines has been prepared by the reaction of tetraorganodiphosphines with chlorodiphenyl or dichlorophenyl phosphine and characterized by 31P and 13C NMR spectra.
