Recently, the biphasic hydrocarboxylation of olefins into carboxylic acids catalyzed by water-soluble palladiumcomplexes has been described in Catalysis Letters as a novel and attractive process for the direct synthesis of carboxylic acids [1]. This interesting new development in the area of the biphasic catalysis had also been reported by ourresearch group in New Journal of Chemistry [2,3]. This independent and simultaneous discovery of the biphasichydrocarboxylation of olefins by two research groups shows undoubtedly that two-phase catalysis is presently one of the most active areas of catalysis research.
