    • Bosnich reported that chelating diphosphines such as 2,4-bis(diphenylphosphino)pentane and 1,3-bis(diphenylphosphino)butane can adopt various conformations. They attribute the generation of an achiral ligand conformation in the hydrogenation of amino acids to reduced enantioselectivity. MacNeil, P. A.; Roberts, N. K.; Bosnich, B. J. Am. Chem. Soc. 1981, 103, 2273.
