Formation of a Rhenium(VII) Phosphonio−Methylidyne Complex
The rhenium(VII) phosphonio−methylidyne complex [Re(NtBu){C−P(NEt2)3}Cl3] (3) is obtained via interaction of an imido ligand in [Re(NtBu)2Cl3] (1) with the phosphorus ylide (Et2N)3PCH2. The isolation of all the intermediates and products of this reaction allows us to postulate a mechanism in which...

Zusammenfassung: | The rhenium(VII) phosphonio−methylidyne complex [Re(NtBu){C−P(NEt2)3}Cl3] (3) is obtained via interaction of an imido ligand in [Re(NtBu)2Cl3] (1) with the phosphorus ylide (Et2N)3PCH2. The isolation of all the intermediates and products of this reaction allows us to postulate a mechanism in which the amine, formally generated from the imido ligand, is trapped by the Lewis acid 1 with formation of [Re(NtBu)3Cl] (4) and [(Et2N)3P−CH3]+[Re(NtBu)2Cl4]- (6). 3 and 6 have been structurally characterized. |
