25. 7c In a series of bidentate chelating phosphines containing xanthene-like ligand backbones, the bite angle was varied from 102° to 131°, with minimal change in the steric or electronic properties of the ligand. The resulting n:i ratio increased from 6.7 to 80.5 in the hydroformylation of 1-octene at 80 °C.
