Triorganobismuthines containing a chiral centre at the metal atom have been prepared by selective bromodearylation of mixed triarylbismuthines, followed by reaction of the resulting chiral diarylbromobismuthines with arylmagnesium bromides.The NMR spectra of some of the new compounds exhibit diastereotopic effects, associated with the chirality, indicating that the bismuthines have a stable pyramidal configuration.
