This mini review presents recent applications of polymer-supported catalyst in different green synthetic approaches, and is focused on the use of these types of catalysts in phase transfer catalysis processes. Phase transfer catalysis is now a well established method in organic synthesis in both industry and academia, being recognized as a versatile method because of its simple experimental operations, mild reaction conditions, inexpensive and environmentally benign reagents and solvents. The discussions involved only some limited aspects related to the use of polymer-supported catalysts in phase transfer catalysis especially concerning ammonium and phoshonium catalysts and cinchona grafted on organic supports. The illustration of efficiency and reusability but also highlights the scope and limitations associated with the supported catalytic systems from a green chemistry view are presented.
Keywords: Polymer-supported, catalyst, green, phase transfer catalysis.
