1-Diphenylphosphinopropan-2-on-hydrobromide (1a), 2-Diphenylphosphino-1-phenylethan- 1-on-hydrobromide (2a), and 1,3-Bis(diphenylphosphino)propan-2-on-bis(hydrobromide) (3a) were prepared by the reaction of the corresponding β-bromo-ketones with diphenyl(trimethylsilyl)phosphine. By treatment with NaOH the hydrobromides 1a-3a were converted into the ketones 1b-3b. The reactions of 1a-3a with (R)-(+)-1-phenylethylamine were investigated.
