Two-phase reactions are reviewed which consist of liquid-liquid and solid-liquid phase systems with quaternary ammonium and phosphonium salts and crown ethers as phase transfer catalysts. Both the working mechanism and the synthetic applications of the phase transfer reactions are given including carbene reactions, C-alkylations, nucleophilic substitutions, ylide reactions, oxidation and reduction, and others.
