Inrecentyearsthechoiceofagivensolventforperformingareactionhas

become increasingly important. More and more, selective reagents are used for

chemical transformations and the choice of the solvent may be determining for

reaching high reaction rates and high selectivities. The toxicity and recycling

considerations have also greatly influenced the nature of the solvents used for

industrialreactions. Thus, thedevelopmentof reactionsinwaterisnotonly

important on the laboratory scale but also for industrial applications. The per-

formance of metal-catalyzed reactions in water for example has led to several

new hydrogenation or hydroformylation procedures with important industrial

applications. The various aspects of organic chemistry in water will be present-

ed in this book. Recently, novel reaction media such as perfluorinated solvents

or supercritical carbon dioxide has proven to have unique advantages leading

to more practical and more efficient reactions. Especially with perfluorinated

solvents,newbiphasiccatalysesandnovelapproachestoperformorganic

reactions have been developed. These aspects will be examined in detail in this

volume.

This book tries to cover the more recent and important new solvents or solvent

systems for both academic and industrial applications.

Great,thank you very much.
