Mj. Hannon et al., Paper: a cheap yet effective chiral stationary phase for chromatographic resolution of metallo-supramolecular helicates, CHEM COMMUN, (12), 2001, pp. 1078-1079
Simple paper chromatography using brine as an eluent affords the two enanti
omers of metallo-supramolecular triple-helicates, The technique may be scal
ed up for preparative resolution by using cellulose columns in conventional
column chromatography.
