Two new dithia‐crowns containing a hydroxy group and 1,4,7,10‐tetrathia‐18‐crown‐6 containing an allyl‐oxymethyl substituent were prepared in good yields. Two of these crowns were covalently attached to silica gel. The silica gel‐bound thia‐crowns were used to separate gold( III ), palladium( II ), silver( I ) and mercury( II ) ions from an aqueous 0.1 M nitric acid solution which also contained 1.0 M ferric chloride.
