1. Phase transfer catalysis (PTC): transferring reagents and/or catalysts to the organic phase

Phase transfer catalysis (PTC) is now a well-established technique, widely used in synthetic chemistry and applied in many industrial processes. Here, we present the principle of phase transfer catalysis and its advantages for the development of more eco-friendly processes, as well as its main applications and most salient recent developments. For a complete and detailed overview of the many applications of phase transfer catalysis, the reader is referred to the articles [J1192] [J1230v2] in this database and to the works cited in the references.
