Patent number: 5777121Abstract: 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).sub.d (Rf).sub.e. (Rf).sub.e is at least one fluorous group and e is a whole number. (R).sub.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.Type: GrantFiled: June 28, 1996Date of Patent: July 7, 1998Assignee: University of PittsburghInventors: Dennis P.
