diisopropyl spiro bis(isoxazoline) ligands, anti‐i‐Pr‐SPRIX and syn‐i‐Pr‐SPRIX, were designed and synthesized. Their catalytic utility, X‐ray crystallographic analyses, and complexation studies demonstrated the structuralfeatures of tetraisopropyl spiro bis(isoxazoline) ligand, i‐Pr‐SPRIX, which is a prominent ligand in various enantioselective Pd catalytic processes: All i‐Pr groups work in collaboration
