%A M Matsugi %A DP Curran %J Organic Letters %T Reverse fluorous solid-phase extraction: A new technique for rapid separation of fluorous compounds %X Fluorous-tagged compounds can rapidly be separated from organic (non-tagged) compounds by the new separation technique of reverse fluorous solid-phase extraction (r-fspe). In a reversal of the roles of solid and liquid phases in standard fluorous spe, a mixture is charged to a polar solid phase (standard silica gel) and then eluted with a fluorous solvent or solvent mixture. The organic components of the mixture are retained, while the fluorous components pass. %N 16 %P 2717 - 2720 %V 6 %D 2004 %R 10.1021/ol049040o %L pittir19869
