Process for the preparation of Binaphthylderivaten

摘要

The production of H8-1,1'-bi-2-naphthyl derivatives is by selective reduction of a binaphthyl derivative with hydrogen, together with a catalyst containing at least one metal of Pt, Ir, Os, Pd, Rh, Ru, Ni, Co and Fe on a carrier. The production of H8-1,1'-bi-2-naphthyl derivatives of formula (I) is by selective reduction of a binaphthyl derivative of formula (II) with hydrogen, together with a catalyst containing at least one metal of Pt, Ir, Os, Pd, Rh, Ru, Ni, Co and Fe on a carrier.
