Abstract New types of Lewis acids as water-stable catalysts have been developed. Metal salts such as rare earth metal triflates can be used in carbon_carbon bond-forming reactions in aqueous media. These salts can be recovered after the reactions and reused. Furthermore, Lewis acid_surfactant-combined catalysts, which can be used for reactions in water without using any organic solvents, have been also developed. Finally, Lewis acid catalysis in supercritical carbon dioxide has been…

Activation of Chemical Substrates in Green Chemistry
The stability and low polarization of organic molecules forces to use an aggressive chemical or heat to activate (one of) the reagent(s). Addition of an activator worsens the atom economy since spent
The Intermediates in Lewis Acid Catalysis with Lanthanide Triflates
TLDR
Spectroscopic data of the gaseous ions accompanied by theoretical calculations reveal that the difference between catalytic efficiencies of ytterbium and dysprosium ions can be explained by their different electrophilicity.
