Beschreibung

Anwendung

(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. 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.
