Reaktionen von Quadratsäure mit Triphenylphosphin‐Platin(0)‐Verbindungen

Abstract: Quadratsäure zeigt gegenüber Pt0‐Verbindungen drei Reaktionsmöglichkeiten: Der Säurecharakter der Quadratsäure kommt bei der Bildung des kationischen Hydridkomplexes [HPt(PPh3)3]⊕ [HC4O4]⊖ (1) aus Pt(PPh3)4 zum Ausdruck; mit (PPh3)2Pt(C2H4) entsteht dagegen der Olefinkomplex 2. Erhitzen von 1 bzw. 2 auf 130°C liefert unter Öffnung des Vierrings das Dihydroxyplatinacyclopentendion 3.

“…Platinum, palladium, and nickel isocyanide complexes were prepared according to published methods. Reaction of [ Pt,(2,4, Me,C,H -To a solution of (4a) (0.05 g, 0.083 mmol) in benzene (15 ml) was added iodine (0.03 g, 0.12 mmol) at room temperature. After 1 h, the solvent was removed and hexane was added to give orange crystals of [Pd(2,6-Me2C,H,NC),12] (0.049 mg, 95%).…”
