Abstract

Anion-catalyzed phase-transfer catalysis was evidenced in the diazo-coupling reactions of the arenediazonium ion with a range of diazophile components in liquid-liquid-and liquid- solid two-phase systems. The tetrakis [3, 5-bis (trifluoromethyl) phenyl] borate ion was effective as an anionic catalyst to accelerate the reactions. Comparisons of the reaction rates in the two-phase system with those in solution systems indicated that the acceleration was ...
