Synthese von Tetrakis-(trifluorphosphin)-platin(0) und -palladium(0)

Abstract: Das aus Aziridin und atherischer Fluoroborsaure erhaltliche [l] Aziridinium-tetrafluoroborat ( I ) addiert sich an Nitrile (2) unter Bildung von A*-Imidazolinium-fluoroboraten (3) :Die Verbindung ( I ) wird rnit der doppelten bis dreifachen molaren Menge (2) ein bis zwei Tage auf 100°C erhitzt. Nach Abdestillieren von uberschiissigem (2) im Vakuum setzt Natriummethylat das Imidazolin aus dem Salz (3) in Freiheit. Die Base wird durch Destillation gereinigt. N-Benzylidenanilin (4) setzt sich rnit (1) (Molverhalt… Show more

“…4 ] are distinctively different, there is a striking qualitative similarity of the 31 P NMR spectrum. [4] From this fact we conclude that the structure of the neutral cluster is similar, and is also composed of four interlinked square-planar [Pt 2 PtA C H T U N G T R E N N U N G (PF 3 ) 2 ] units. We have repeated the preparation of this material, and can confirm all results, especially that crystals by sublimation do not diffract at all.…”

“…The third compound is the PF 3 homologue to the compound NiðCOÞ 4 ; which is well known to form the only carbonyl spontaneously from an element. As was shown first by Kruck, PtðPF 3 Þ 4 is obtained from PtCl 4 by applying PF 3 at elevated pressures of more than 300 bars [16,17]. Compared to these rather hostile conditions, Chatt found out that at atmospheric pressure, the synthesis of volatile cis-Cl 2 PtðPF 3 Þ 2 was possible ðbp : 2401CÞ [18].…”
