Reactions of Coordinated Ligands, IV. Cyclotriphosphane Complexes (RP)3m (m = 1, 2, 3) by Dehalogenation of RPBr2Cr(CO)5 with Magnesium

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
