A coincident spontaneous resolution system for racemic 1,1'-binaphthyl-2,2'-dicarboxylic acid and 1,2-diphenylethylenediamine induced by water.
Spontaneously resolvable conglomerate crystals are obtained by combining racemic (rac)-1,1'-binaphthyl-2,2'-dicarboxylic acid and rac-1,2-diphenylethylenediamine, and this spontaneous resolution system is induced by water which is present in the crystallization solvent.
