说明

應用

(1R)-2,2′-Bis[(S)-(4-methylphenyl)sulfinyl]-1,1′-binaphthalene (p-tolyl-BINASO) is a bis-sulfoxide ligand that can be used to prepare cationic palladium and platinum complexes. These complexes are employed as catalysts in hydroboration and diboration reactions.[1] It can also be used to prepare the precatalyst [p-tol-BINASO}RhCl]₂ for the synthesis of chiral arylcycloketones by the 1,4-addition reaction of arylboronic acids to cyclic α,β-unsaturated ketones.[2]
