8′-Iodo-8-[1-(1′-phenylthio)ferrocenyl]-1,1′-binaphthyl, a precursor of chiral phosphines, and 8′-(4-methylphenyl)-8-[1-(1′-phenylthio)ferrocenyl]-1,1′-binaphthyl, a model compound for the preparation of charge-transfer complexes were synthesized via Suzuki coupling reactions of ferrocenylboronic acids and 8-substituted 8′-iodo-1,1′-binaphthyls. Sequential substitution of 8,8′-diiodo-1,1′-binaphthyl provided a facile method of generating unsymmetrical 8,8′-disubstituted 1,1′-binaphthyls.
