A novel type of catalysts for asymmetric oxidative coupling of 2-naphthol
Stereochemically inert, positively charged chiral octahedral complexes of Co III and Cr III were used as catalysts for asymmetric oxidative coupling of 2-naphthol. The reaction product 1,1´-bi-2-naphthol was produced with a yield of up to 74% and enantiomeric excess of up to 22%. The reduction and o...

Summary: | Stereochemically inert, positively charged chiral octahedral complexes of Co
III
and Cr
III
were used as catalysts for asymmetric oxidative coupling of 2-naphthol. The reaction product 1,1´-bi-2-naphthol was produced with a yield of up to 74% and enantiomeric excess of up to 22%. The reduction and oxidation potentials of a series of Co
III
and Cr
III
cationic complexes were measured. |
