NO-Feng-PDiPPPi, L-PiPr2, 99%

Product Introduction

N,N'-Dioxides (Bis-N-oxide Compounds) represent an ideal class of ligands and catalysts for asymmetric synthesis. These chiral ligands break through the traditional requirement for highly rigid ligand frameworks. Much like a pair of nunchaku, they combine both rigidity and flexibility, enabling precise control over how reactants approach and interact during a chemical transformation. By regulating the spatial arrangement and orientation of substrates in the catalytic process, N,N'-dioxide ligands promote bond formation in a predictable and highly enantioselective manner, making them powerful tools in modern asymmetric catalysis.
