Oxidative Addition von 4‐Isonitroso‐3‐R‐isoxazol‐5(4 H )‐onen und Isoxazolonen an Ethylenbis(triphenylphosphan)platin(O)

Abstract: 4-Isonitroso-3-R-isoxazol-5(4H)-oneWir fanden, daB sich die Verbindungen 1 oxidativ an Platin(0) unter Bildung von truns-Hydridobis(triphenylphosphan)platin(II)-Komplexen mit den jeweiligen Anionen der 4-Isonitroso-3-R-isoxazol-5(4H)-one addieren. Die Reaktion Iauft bei Raumtemperatur in Toluol ab.Die schwach gelben Verbindungen 2 weisen intensive IR-Banden auf bei 2173 (2a) bzw. 2163 cm-' (2b) (fest in KBr), die Pt -H-Valenzschwingungen zuzuordnen sind.

“…In (E)-trans-4 and (E)-trans-6 the Pt-N bond lengths are significantly longer (2.134(3) and 2.1393(16) respectively), due to the trans influence exerted by triphenylphosphine and already observed for some dipyridyl-and piperazino-Pt(II) complexes. [4a] Indeed, these bond lengths can be compared with those reported for trans-hydrido (3-methylisoxazol-4,5-dion-4-oximato-N)bis(triphenylphosphino)platinum(II) [14] (2.15(3) Å) and for some platinum acetyl(N-oxime) derivatives [15] (bond lengths ranging from 2.104(3) to 2.137(3) Å), where the N-coordinated oxime ligand is trans to residues (hydride and acetyl) characterized as well by a strong trans influence. Couples of molecules of (E)-trans-6 interacts by π-stacking of phenanthryl moieties at distance of about 3.5 Å, as shown in Figure S3.…”
