    Description / Table of Contents: Element-Organic Amine/Imine Compounds, XXVI. Aminoiminophosphanes as Bridging Ligands in triangulo-Clusters of Zerovalent PlatinumThe interaction of PtL3 (2), L = R1R2N—P = NR3 (1), with tert-butyl isocyanide as well as the reaction of Pt3(μ-CNtBu)3(CNtBu)3 (5) with 1 afford the triangulo-platinum clusters Pt3(μ-CNtBu)(μ-L)2(CNtBu)3(3). Pt3(μ-L)3(CO)3 (4) is formed from 2 and CO. The structures of 3 and 4 were established by 1H, 13C{1H}, 31P{1H} and 195Pt{1H} NMR spectroscopy. 3a and 4a have been characterized additionally by an X-ray structure analysis.
    Notes: Die Umsetzung von PtL3 (2), L = R1R2N—P = NR3 (1), mit tert-Butylisocyanid bzw. von Pt3(μ-CNtBu)3(CNtBu)3 (5) mit 1 ergibt die Platin-Dreikerncluster Pt3(μ-CNtBu)(μ-L)2(CNtBu)3(3). Pt3(μ-L)3(CO)3 (4) entsteht aus 2 und CO. 3 und 4 wurden durch 1H-, 13C{1H}-, 31P{1H}- und 195Pt{1H}-NMR-Untersuchungen, 3a und 4a zusätzlich durch eine Röntgenstrukturanalyse charakterisiert.

    Description / Table of Contents: Element-Organic Amine/Imine Compounds, XXIV. Tris[(tert-butylimino)[tert-butyl(trimethylsilyl)amino]phosphane}platinum(0) - a Useful Synthesis Building BlockThe reaction of PtL3 (4) (L = RN = P—NRR′, R = tBu, R′ = SiMe3) with the alkenes C2Cl3H, C2Cl4, C2H2(CN)2, and C2(CN)4 affords the platinum phosphazene complexes 1a, 1, 5a, and b; with diphenylacetylene 6 is formed. Water adds to the P = N bonds of 1 and 5 with formation of the chelate complexes 2 and 9. At ambient temperature 2 isomerizes to the vinyl chelate complex 3 whose structure has been elucidated by an X-ray analysis. From 4 and the double ylide R′RN—P(S) = NR the four-membered ring L2 (7) is obtained. 4 and CS2 give the thiocarbonyl complex [L(CS)Pt(μ-S)]2 (8).
    Notes: Die Umsetzung von PtL3 (4) (L = RN = P—NRR′, R = tBu, R′ = SiMe3) mit den Alkenen C2Cl3H, C2Cl4, C2H2(CN)2 und C2(CN)4 ergibt die Platin-Phosphazen-Komplexe 1a, 1, 5a und b; mit Diphenylacetylen entsteht 6. Wasser addiert sich an die P = N-Bindungen von 1 und 5 unter Bildung der -Chelatkomplexe 2 und 9. Verbindung 2 lagert sich bei Raumtemperatur in den Vinyl-Chelatkomplex 3 um, der durch eine Röntgenstrukturanalyse charakterisiert wurde. 4 und das Doppelylid R′RN—P(S)=NR ergeben den Vierring L2 (7), mit CS2 entsteht der Thiocarbonyl-Komplex [L(CS)Pt(μ-S)]2 (8).

    Description / Table of Contents: Element-Organic Amine/Imine Compounds, XXII. λ3-Phosphazene Complexes of Zerovalent PlatinumThe reaction of Pt(COD)2 (COD = 1,5-cyclooctadiene) with the λ3-phosphazene RR'N—P=NR, R = (CH3)3C, R' = (CH3)3Si(1), gives the platinum(0) complex PtL3 (2) (L = λ3-phosphazene 1) whose structure has been elucidated by an X-ray analysis. 2 is used for the synthesis of the platinum(0) compounds PtL2L' (L' = R3M, M = P→b) (3) and PtLL2' (L' = R3P) (4).
