Page/Page column 3; 19, (2008/06/13)
One aspect of the present invention relates to a method of purifying radiolabelled compounds comprising a) loading onto a fluorous polymer a radiolabelled compound precursor comprising a fluoroalkyl tin moiety; b) reacting the radiolabelled compound precursor with a radiolabel delivering compound to give a radiolabelled compound, wherein the fluoroalkyl tin moiety is replaced by a radiolabel; and c) eluting the radiolabelled compound from the fluorous polymer.

The present invention provides a method for carrying out a chemical reaction comprising the steps of forming an organic/fluorous solubilizing liquid phase comprising a solvent system. The solvent system is selected or adapted to substantially solubilize a fluorous reaction component or components (that is, a fluorous reagent, a fluorous catalyst and/or a fluorous reactant). The "fluorous reaction component" is functionalized to comprise at least one fluorous moiety having the formula -(R)d (Rf)e. (Rf)e is at least one fluorous group and e is a whole number. (R)d is an organic (for example, hydrocarbon) spacer group, which may be present or absent, and d is an integer equal to at least zero. The solvent system is also adapted to substantially solubilize an organic reaction component or components. After the reaction occurs in the organic/fluorous solubilizing liquid phase, a phase separation into at least a fluorous phase and an organic phase is effected. The present invention also provides a chemical compound of the formula XM?(R) (Rf)!3, wherein M is Ge or Sn and X is an atom or group selected to react with an organic reaction component or components.
