Axial chirality is generated upon complexation of the novel triphos ligand with a metal. In the presence of the diamine dm-dabn, isomerization to the enantiopure triphos–Ru complex was observed. The dm-dabn ligand of the Ru complex exchanges with dpen at room temperature without racemization. dm-dabn=3,3′-dimethyl-2,2′-diamino-1,1′-binaphthyl, dpen=1,2-diphenylethylenediamine.
