So soft and yet so strong ! Bismuth Lewis acids undergo efficient adduct formation with soft donors such as SPMe 3 and SePMe 3 . The 31 P NMR chemical shift can be used as an easily accessible experimental parameter for the assessment of soft Lewis acidity. In particular, cationic bismuth compounds are exceptionally strong and soft Lewis acids. More information can be found in the Full Paper by J. Ramler and C. Lichtenberg on page 10250.
