- W2037925503 abstract "Durch Reduktion von FeCl2 mit Mg wird in Gegenwart von Me2PCH2PMe2 der pentakoordinierte Eisen(0)-Komplex (Me2PCH2PMe2)2FeMe2PCH2PMe2 (5), in Gegenwart von Me2P[CH2]3PMe2 der Hydridoeisen(II)-Komplex 6b erhalten, der durch eine reversible intramolekulare C,H-Addition im Lösungsgleichgewicht mit seinem tetrakoordinierten Eisen(0)-Isomeren (Me2P[CH2]3PMe2)2Fe (6a) steht. Durch Reaktion von 6a mit einer Reihe von kleinen Molekülen (CO, CO2, N2, PR3) läßt sich das Gleichgewicht zur Eisen(0)-Stufe verschieben. 5 und 6 werden bezüglich der C,H-Aktivierung mit analogen PMe3- und Me2P[CH2]2PMe2-Eisenkomplexen 1 und 2 verglichen. Complexes with Phosphinomethanes and -methanides as Ligands, VIII1). – Iron(0) Complexes with Me2PCH2PMe2-and Me2P[CH2]3PMe2 Ligands: C–H Activation versus Pentacoordination By reduction of FeCl2 with Mg in the presence of Me2PCH2PMe2 the pentacoordinated iron(0) complex (Me2PCH2PMe2)2FeMe2PCH2PMe2 (5) is obtained. In the presence of Me2P[CH2]3PMe2 the hydridoiron(II) complex 6b is formed. In solution 6b is in equilibrium with its tetracoordinated iron(0) isomer (Me2P[CH2]3PMe2)2Fe (6a) by a reversible intramolecular C–H addition process. This equilibrium is shifted to the iron(0) form by reaction with small molecules (CO, CO2, N2, PR3). 5 and 6 are compared with the analogous PMe3- and Me2P[CH2]2PMe2 iron complexes 1 and 2 with respect to their C,H-activation." @default.
