[368454-69-7] C60H46N2O2 (MW 826.01) (chiral salen ligand for enantioselective transition metal-catalyzed reactions, including Ru-, Co-, and Ir- catalyzed cyclopropanation of alkenes,1 Ti-catalyzed sulfoxidation and Ru-catalyzed sulfimidation of sulfides,2 Mn-, Ru-, and Nb- catalyzed epoxidation of alkenes,3 Ir- and Mn- catalyzed CH bond functionalization,4 Ru-catalyzed oxidative kinetic resolution of sec-alcohols,5 and Zr- catalyzed asymmetric Baeyer–Villiger oxidations6) Solubility: soluble in common organic solvents. Preparative Methods: the chiral salen ligand 1 can be rapidly prepared in excellent yield by condensation of (1R, 2R)-1,2-cyclohexanediamine with (R)-3-formyl-2-hydroxy-2′-phenyl-1,1′-binaphthyl 27 in EtOH under an inert atmosphere at ambient temperature for 6 h (eq 1).1b (1) Preparation of optically active metal salen–1 complexes, M(salen), is generally achieved by simply mixing a solution of ligand 1 with an appropriate metal salt at elevated temperature. Handling, Storage, and Precautions: toxicity unknown; use in a fume hood, handle with appropriate safety protection equipment.
