Selective organic reactions using microreactors

Organic reactions using microreactors have attracted significant research interest because of their inherent features such as fast mixing, precise temperature control, and precise residence time control. These features are especially advantages for fast and exothermic reactions, which are difficult to perform using conventional macro-scale batch reactors in a controlled manner. Some examples of such reactions including Friedel-Crafts alkylation, cationic polymerization, and Swern oxidation are described in this article. Other examples are also demonstrated with the special emphasis on multiphase reactions. These examples speak well for the potentiality of microreactors in the enhancement of the ability of organic synthesis to meet demanding expectations in future.
