Reactions of Coordinated Ligands, VIII. Synthesis, Reactivity, and Structure of Molybdenum- and Nickel Carbonyl Complexes of 1,3-Bis(phenylphosphino)propane1,3-Bis(phenylphosphino)propane reacts with Ni(CO)4, C7H8Mo(CO)4, and Mo(CO)6 to produce complexes of the type (CO)nM(PhPH—C3H6—PPhH) (n = 4, M=Mo; n = 2, M=Ni) and oligomers thereof. These compounds were also obtained by the reaction of phosphido complexes (CO)nM(PhPHM′)2 (n = 4, M=Mo, M′=Li; n = 2, M=Ni, M′=Li, Na) with 1,3-dibromopropane. The complexes (CO)nM(PhPH—C3H6—PPhH) may be deprotonated with methyllithium. The reactions of the phosphido complexes thus obtained are discussed. From the meso-form of (CO)2Ni(PhPH—C3H6—PPhH), which crystallizes in the space group Cmc21, an x-ray structure analysis has been performed.
Notes:
1,3-Bis(phenylphosphino)propan reagiert mit Ni(CO)4, C7H8Mo(CO)4 und Mo(CO)6 unter Bildung von Komplexen des Typs (CO)nM(PhPH—C3H6—PPhH) (n = 4, M=Mo; n = 2, M = Ni) und deren Oligomeren. Diese Verbindungen werden auch bei Umsetzung von Phosphidokomplexen (CO)nM(PhPHM′)2 (n = 4, M=Mo, M′=Li; n = 2, M=Ni, M′=Li, Na) mit 1,3-Dibrompropan erhalten. Die Komplexe (CO)nM(PhPH—C3H6—PPhH) lassen sich mit Methyllithium deprotonieren. Über Reaktionen der dabei gebildeten Phosphidokomplexe wird berichtet. - Von der Mesoform von (CO)2Ni(PhPH—C3H6—PPhH) (1), das in der Raumgruppe Cmc21 kristallisiert, wurde eine Röntgenstrukturanalyse durchgeführt.
