Dibromophosphines, RPBr2, are obtained by reaction of tetrabromomethane with 7-substituted 7-phosphanorbornenes in toluene at ca. 100 °C. The phosphanorbornenes are obtained in situ by cycloaddition of N-phenylmaleimide with 1-substituted 3,4-d

Aminophosphines RP(NR'2)2 (R = Ph, cyclo-Hex, (-)-Men, t-Bu; R' = Me, Et) as ligands L in complexes (CO)5ML (M = Cr, Mo, W) have been found to react with HX (X = Cl, Br) mainly under substitution of only one of the two dialkylamino groups by halogen.Under similar conditions the free phosphines are converted into the dihalogenphosphines.The halogenamino complexes (CO)5MPRXNR'2 are readily accessible by this reaction, the mechanism of which is discussed.The preparation of several new compounds RP(NR'2)2 is reported.

Compounds RPBr2Cr(CO)5 (R = Me, Et, i-Pr, t-Bu, c-Hex, (-)Menthyl, Ph) and RPBr2W(CO)5 (R = (-)Menthyl, Ph) are obtained from M(CO)5THF and organodibromophosphane.Dehalogenation of the chromium complexes with magnesium in THF leads to (RP)3m (m = 1, 2, 3) with m depending on the bulkiness of R.When dissloved in THF the binuclear complexes (m = 2) are gradually converted into mononuclear compounds.The isomeric structure of the cyclotriphosphane complexes is deduced from their 31P NMR spectra. - Keywords: Carbonylorganodibromophosphane Complexes, Carbonyltriorganocyclotriphosphane Complexes, 31P NMR Spectra

Complexes (CO)5MR(X)PP(X)RM(CO)5 (R = aryl; X = Br, I; M = Cr, W) (II) have been prepared by reaction of (CO)5M*THF with the corresponding diphosphanes RXPPXR.The disproportionation, R(X)PP(X)R (RP)n + RPX2, which is observed in solutions of the free
