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
SYNTHESIS AND INFRARED STUDY OF (C6H5)nPX3-nCr(CO)5 (X=Cl, Br, I, H; n=0-3) AND (C6H5)2PRCr(CO)5 (R=METHYL, ETHYL, i-PROPYL, t-BUTYL) COMPOUNDS

A method for the preparation of (C6H5)nPX3-nCr(CO)5 complexes in the crystalline state is described.The carbon-oxygen stretching vibration, νCO(A1 eq.), of the complexes with X=Cl, Br, I is mainly determined by the inductive effect of the (C6H5)nPX3-n group.For X=H, the νCO band is defined by the concomitant influence of the ?, ? and steric effects.
