Gas-liquid biphasic organic synthesis

Gas—Liquid Biphasic Organic Synthesis Table 6.8 Continuous photooxygenation of various substrates by singlet oxygen. 

Catalytic biphasic reactions, including their aqueous variants, are widely used for the catalytic synthesis of organic products. Catalysts, various types of water-soluble ligands, synthetic uses, industrial applications, and their advantages over conventional homogeneously catalyzed reactions are well documented (e.g. [1-3]). Table 1 presents few examples of reactions performed in an aqueous gas/liquid-liquid medium with a homogeneous complex catalyst soluted either in the aqueous phase or organic phase. 

In future, a complete quantitative analysis on the basis of chemical reaction engineering principles of homogeneously catalyzed gas-liquid-liquid reactions is needed to improve known aqueous biphasic reactions as well as to find new, highly active and selective homogeneous catalysts for organic synthesis.
