Bequeme Synthese von cis-1,2- Bis(diphenylphosphino)ethanplatin(II)- acetyliden / Convenient Synthesis of cis-1,2-Bis(diphen3dphosphino)- ethane-platinum (II) -acetylides

Abstract

Abstract The title compounds (1) are obtained in quantitative yield from the reaction between dppePtCl2 (2) and alkynyl stannanes (CH3)3 Sn - C ≡ C-R (3) or (CH3)2Sn(C ≡ C-R)2 (4) in boiling tetrahydrofurane. The complexes 1 have been characterised by multinuclear NMR (13PC, 31P, 195Pt).
