Abstract : A chiral dimethylpyridino-18-crown-6 ligand was attached to silica gel by first forming an allyloxy-substituted crown. This material was treated with triethyoxysilane and then coated and covalently attached to silica gel. This report shows the synthesis of the silica gel-bound chiral crown and its use in separating alpha-(1-naphthyl)ethylammonium perchlorate into its (R)- and (S)- forms.
