Reactions of Tertiary Phosphines with 3-Halogen-1,2-naphthoquinones as a New Synthetic Approach to 3,3′,4,4′-Tetrahydroxy-1,1′-binaphthyls

详细

A mild and efficient method for the synthesis of new tetrahydroxy-1,1′-binaphthyls containing a halogen atom in the position 3 of the naphthalene moiety was developed. The structure of the tetrahydroxy-1,1′-binaphthyls complexes with the corresponding phosphine oxides was established by NMR spectroscopy.
