摘要：
Sulfonation of chiral aryl phosphanes occurs readily in high yields when they contain C6H4‐p‐(CH2)3‐C6H5 groups. The diphosphane 1 synthesized in this way is surface active and increases the activity and selectivity of Rh catalysts for the hydrogenation of cinnamic acid derivatives in two‐phase systems.
