ABSTRACT
Iron complexes bearing the dibenzophospholyl (DBP) ligand have been prepared. Reaction of DBP-Li with CpFe(CO)[sub 2] Br gave [(�[sub 2] -DBP)Fe[sub 2] Cp[sub 2] (CO)[sub 4] ]Br and reaction of DBP-Li with CpFe(CO)[sub 2] I gave [(�[sub 2] -DBP)Fe[sub 2] Cp[sub 2] (CO)[sub 4] ]I. Reaction of bis(1,1'-dibenzophospholyl) and [CpFe(CO)[sub 2] ][sub 2] yielded a mixture of cis- and trans-(�[sub 2] -DBP)[sub 2] Fe[sub 2] Cp[sub 2] (CO)[sub 2] . The mixture was also obtained on heating of [(�[sub 2] -DBP)Fe[sub 2] Cp[sub 2] (CO)[sub 4] ]X (X = Br, I). The ligands are sigma-bonded through the phosphorus atom in all complexes. The compounds were characterized by [sup 1] H, [sup 13] C, and [sup 31] P NMR and IR spectroscopies, mass spectrometry, micro analysis, and X-ray diffraction.Key words: dibenzophospholyl, iron, heterocycle.On a pr�par� des complexes du fer portant le ligand dibenzophospholyle (DBP). La r�action du DBP-Li avec le CpFe(CO)[sub 2] Br conduit � la formation du [(�[sub 2] -DBP)Fe[sub 2] Cp[sub 2] (CO)[sub 4] )]Br alors que la r�action du DBP-Li avec le CpFe(CO)[sub 2] I conduit � la formation du [(�[sub 2] -DBP)Fe[sub 2] Cp[sub 2] (CO)[sub 4] )]I. La r�action du bis(1,1'-dibenzophospholyle) avec le [CpFe(CO)[sub 2] ][sub 2] conduit � un m�lange des isom�res cis- et trans- du (�[sub 2] -DBP)Fe[sub 2] Cp[sub 2] (CO)[sub 4] ]X (X = Br, I). Dans chacun de ces complexes, les ligands sont li�s aux atomes de phosphore par des liaisons sigma. Les compos�s ont �t� caract�ris�s par RMN du [sup 1] H, du [sup 13] C et du [sup 31] P, spectroscopie IR, spectrom�trie de masse, microanalyses et diffractions des rayons X.Mots cl�s : dibenzophospholyle, fer, h�t�rocycle.[Traduit par la R�daction]
