General Description

1,4-Bis(diphenylphosphino)butane (dppb) is a bidentate diphosphine ligand commonly used in rhodium-catalyzed reactions, such as hydrothiolation, where it contributes to high Z-selectivity and enantioselectivity. Its flexible butane backbone allows for adaptable coordination geometry, making it effective in forming stable metal complexes for catalytic applications, including dynamic kinetic resolution and the synthesis of bioactive molecules.
