Abstract
Crystallization-induced diastereomeric transformation of a solid solution salt composed of a chiral primary amine, 4-cyano-1-aminoindane, and di-p-toluoyl-l-tartaric acid was achieved using (pentamethylcyclopentadienyl)iridium(III) diiodide dimer as a racemization catalyst. The enrichment continued until the composition of the solid phase was in equilibrium with that of the liquid phase at 0% diastereomeric excess.
期刊介绍：
The aim of Crystal Growth & Design is to stimulate crossfertilization of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the industrial application of crystalline materials.
Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials. Synergistic approaches originating from different disciplines and technologies and integrating the fields of crystal growth, crystal engineering, intermolecular interactions, and industrial application are encouraged.
