ResumoAn extremely high coupling constant of 28954 Hz ( 1 J ( 195 Pt 119 Sn))—the highest one‐bond spin‐spin coupling yet found—has been measured for [PtCl(SnCl 3 )(PEt 3 ) 2 ]. In combination with SnCl 2 , platinum‐phosphane complexes are excellent homogeneous catalysts for hydrogenation and hydroformylation reactions. 195 Pt‐NMR spectroscopy is extremely sensitive to changes of the coordination sphere and is therefore well suited to the study of such catalysts.
