Phanephos is an organophosphorus compound with the chemical formula (C2H4)2(C6H3PPh2)2 (Ph = C6H5). It is a white solid that is soluble in organic solvents. It is an example of a chiral diphosphine used in asymmetric hydrogenation. Many substituents have been introduced in place of the phenyl groups e.g. i-Pr C6H11 etc and a variety of chiral phosphine ligands have been reported in asymmetric catalysis since the 1960s.
