ACCELERATION OF SOLID-LIQUID TWO-PHASE REACTION BY MEANS OF ALUMINA-WATER-ULTRASOUND. A SUBSTITUTE FOR A PHASE TRANSFER CATALYST

Article abstract of DOI:10.1246/cl.1984.725

Combined use of alumina, a trace of water, and ultrasound greatly accelerated a solid-liquid two-phase nucleophilic substitution by cyanide ion in nonpolar organic solvents.The efficiency under the optimum conditions were compared with that of phase transfer catalysts such as 18-crown-6.
