- W4249954744 abstract "Ausgehend von MePCl2 sind die Eisenkomplexe (CO)4Fe – PMe(NMe2)2) (1), (CO)4Fe – PMe-(NMe2)Cl (2), (CO)4Fe – PMe(NMe2)H (3) und (CO)4Fe – PMe(H)Cl (4) zugänglich. Von diesen liefern die PCl-Verbindungen 2 und 4 mit Carbonylmetallaten die Metall-Metall-verknüpften funktionellen Zweikernkomplexe (μ-PMeNMe2)FeCo(CO)7 (5), (μ-PMeH)FeCo(CO)7 (6a), (μ-PMeH)FeMn(CO)8 (7) und (μ-PMeH)Fe2(CO)6NO (8). In den Zweikernkomplexen (μ-PRH)FeCo(CO)7 (6, R;Me. tBu) tritt mit CCl4 oder CBr4 H/Hal-Austausch zu (μ-PRHal)FeCo(CO)7 (9, Hal;Cl; 10, Hal;Br) ein. Anschließende Umsetzung mit Carbonylmetallaten liefert die Dreikernkomplexe FeCo(CO)7-(μ-RP)-M′ (11, M′;Mn(CO)5; 12, M′;FeCp(CO)2)) und/oder die Hetero-Cluster (μ-RP)FeCo(CO)6(13, M;Mn(CO)4; 14, M;FeCp(CO); 15, M =CrCp(CO)2; 16, M;WCp(CO)2). Von den Cluster 13b und 14b wurden Kristallstrukturbestimmungen durchgeführt. Cluster Construction: Stepwise Formation of μ3PR Trimetal Clusters via P-Hal Compounds Starting from MePCl2 the iron complexes (CO)4Fe – PMe(NMe2)2) (1), (CO)4Fe – PMe-(NMe2)Cl (2), (CO)4Fe – PMe(NMe2)H (3) and (CO)4Fe – PMe(H)Cl (4) are accessible. Of these the PCl compounds 2 and 4 with carbonyl metalates yield the metal-metal bonded functional dinuclear complexes (μ-PMeNMe2)FeCo(CO)7 (5), (μ-PMeH)FeCo(CO)7 (6a), (μ-PMeH)FeMn(CO)8 (7) and (μ-PMeH)Fe2(CO)6NO (8).In the dinuclear complexes (μ-PRH)FeCo(CO)7 (6, R;Me, tBu) CCl4 CBr4 effect H/Hal exchange with formation of (μ-PRHal)FeCo(CO)7 (9, Hal;Cl; 10, Hal;Br). Subsequent reaction with carbonyl metalates leads to the trinuclear complexes FeCo(CO)7-(μ-RP)-M′ (11, M′;Mn(CO)5; 12, M′;FeCp(CO)2)) and/or to the mixed metal clusters (μ-RP)FeCo(CO)6(13, M;Mn(CO)4; 14, M;FeCp(CO); 15, M =CrCp(CO)2; 16, M;WCp(CO)2). Crystal structure determinations were undertaken for the clusters 13b and 14b." @default.
