Optically active 2,2Ј-bis(2-trifluoro-4-aminophenoxy)-1,1Ј-binaphthyl and its corresponding racemate were prepared by a nucleophilic substitution reaction of 1,1Ј-bi-2-naphthol with 2-chloro-5-nitrotrifluorotoluene and subsequently by the reduction of the resulting dinitro compounds. A series of opt
