Phase vanishing method-system for diffusion controlled addition of exothermic reagents through a fluorous membrane

Fluorous solvent in phase-vanishing reactions acts as a phase screen between the bulk reagent and the reaction phase. The unique properties of the fluorous phase enable the stow diffusion-controlled transport of reagent through this bulk membrane and its uniform phase-transition from transport to reaction phase. Slow addition through the whole interface prevents the build-up of localised high concentration of reagent which means that it is possible to perform reactions involving highly reactive reagents at room temperature.
