Aqueous transition-metal catalysis,l to justify research on the use of water in catalytic processes by environmental reasons. Certainly, the trend to get rid of organic solvents is quite common for modern chemical technology. More and more of both end-user products and industrial chemicals, which earlier were invariably associated wi

Water-stable rare-earth Lewis-acid catalysis in aqueous and organic solvents,lectivities, and for the mild conditions used . While various kinds of Lewis-acid-promoted reactions have been developed and many have been applied in industry, these reactions must be carried out under strict anhydrous conditions. The presence of even a small amount of water stops the reaction,
