摘要：
D-2,2'-bis(diphenylphosphino)-1,1'-binaphthyldioxide and 1-2,2'-bis(diphenylphosphino)-1,1'-binaphthyldioxide are produced by reacting d1-2,2'-bis(diphenylphosphino)-1,1'-binaphthyldioxide with optically active camphor-10-sulfonic acid or optically active 3-bromo-camphor-10-sulfonic acid as a resolving agent in a lower alkyl ester of acetic acid containing a lower alkyl carboxylic acid, thereby forming diastereomeric salts, and optically resolving said diastereomeric salts.
