✦ Synopsis
An 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.
