    Notes: Synthesis and Structure of the Polycyclohexaphosphines P6(C5Me5)4 and P6(C5Me5)2The cyclotriphosphine (PC5Me5)3 (1) decomposes in boiling benzene to give the bicyclo[3.1.0]hexaphosphine P6(C5Me5)4 (2) which yields the tricyclo[3.1.0.02.6] hexaphosphine P6(C5Me5)2 (3) in boiling xylene. The structures of 2 and 3 have been determined by 31P-, 13C-, and 1H-NMR spectroscopy and by X-ray crystallography. 3 represents the first member of a new class of polyphosphines. The specific thermolysis of 1 and 2 under comparatively mild conditions is based on the easy homolytic cleavage of P  -  C5Me5 bonds in these compounds.

    Description / Table of Contents: Pentamethylcyclopentadinelyl-Substituted Cyclophosphanes as a Source for Px units in Transition-Metal ComplexesTris(pentamethylcyclopentadienyl)cyclotriphosphane, (Me5C5P)3 (2), reacts with complexes of the type M(CO)3L3 (M = Cr, Mo, W; L = CH3CN) (1a-c) to give the cyclotriphosphorus complexes (η5-Me5C5)M(CO)2 -η3-P3 (3a-c). The complexes 3a and 3c are also formed in the reaction of the bicyclic hexaphosphane P6(C5Me5)4 (5) with 1a and 1c, respectively. In case of the molybdenum compound 1b the cyclotriphosphorus complex 3b or a mixture of 3b, [{(η5-Me5C5)Mo}2 (μ-η6-P6)] (6), and [{(η5-Me5C5)Mo(CO)2} 2(μ-η2-P2)] (7) is formed, depending on the reaction conditions. By irradiation the complex 3b is transferred nearly quantitatively to the tripeldecker complex 6. The reactions described open a new access to transition-metal complexes with naked phosphorus units as ligands.
    Notes: Tris(pentamethylcyclopentadienyl)cyclotriphosphan, (Me5C5P)3 (2), reagiert mit Komplexen des Typs M(CO)3L3 (M = Cr, Mo und W; L = CH3CN) (1a-c) zu den Cyclotriphosphor-Komplexen η5-Me5C5)M(CO)2 -η3-P3 (3a-c). Die Komplexe 3a bzw. 3c entstehen auch bei der Umsetzung des bicyclischen Hexaphosphans P6(C5Me5)4 (5) mit 1a bzw. 1c. Im Fall der Molybdän-Verbindung 1b erhält man je nach Reaktionsführung den Cyclotriphosphor-Komplex 3b oder ein Gemisch aus 3b, [{(η5-Me5C5)Mo}2 (μ-η6-P6)] (6) und [{(η5-Me5C5)Mo(CO)2} 2(μ-η2-P2)] (7). Unter Bestrahlung läßt sich der Komplex 3b nahezu vollständig in den Tripeldecker-Komplex 6 überführen. Die beschriebenen Reaktionen eröffnen einen neuen Zugang zu Übergangsmetallkomplexen mit nackten Phosphor-Einheiten als Liganden.
