1. The interaction of r(+)- or s(-)-2,2'-diamino-1,1'-binaphthalene with a pd/silica catalyst in tetrahydrofuran.

G E Robinson, G Webb, N C Young, S D Jackson. Enantiomer. 2000 Dec; 5(6): 567-70. PMID: 11342292.

The interaction of 2,2'-diamino-1,1'-binaphthalene over a Pd/silica catalyst and its interaction with hydrogen in the system and with the solvent tetrahydrofuran, (THF) has been investigated. Three interactions have been identified, i) conversion of amine groups to hydroxy groups, ii) hydrogenation of one or more of the aromatic rings, and iii) reaction between the amine group(s) and the THF solvent.
