A method of reacting a first compound to produce a second compound includes the step of contacting a first non-fluorous phase including the first compound with a first fluorous phase at a first phase interface. The first compound distributes between the first fluorous phase and the first non-fluorous phase. The method further includes the steps of contacting the first fluorous phase with a second non-fluorous phase at a second phase interface and including at least a third compound in the second non-fluorous phase that reacts with the first compound to produce the second compound. The second compound has a distribution coefficient less than the first compound. This method can, for example be used to separate the second compound from unreacted first compound wherein, for example, the first compound is of a fluorous nature and distributes more readily into (or transports more quickly through) the fluorous phase than does the second compound. In general, the fluorous phase serves as a barrier to prevent the two non-fluorous phases from mixing, but molecules that can migrate through the fluorous phase can pass from one side to the other.
