      Phase transfer catalysis (PTC) has proven to be a highly advantageous strategy for reaction promotion. 1 Phase transfer catalysts facilitate reactions of substances that are heterogeneously distributed in immiscible phases, with catalysis generally operating via the transfer of an anionic species from the aqueous (or solid) phase to the organic by: Since when useful working concepts for the technique of phase-transfer catalysis (PTC) were introduced, the understanding, development, and applica­ tions of this method for conducting organic reactions has expanded exponentially. PTC has brought vast new dimensions and options to chemists and chemical engineers.

      Phase transfer catalysis or interfacial catalysis is a syn­ thetic technique involving transport of an organic or inorganic salt from a solid or aqueous phase into an organic liquid where reaction with an organic-soluble substrate takes place. Over the past 15 years there has been an enormous Author: Lon Mathias. pages. Cost: $ + $ shipping & handling to addresses in the US.

By the mid sixties, Starks had formulated the principles of phase transfer catalysis and had applied for patents on many reactions that others were later to examine in somewhat greater detail. His mechanistic model of phase transfer catalysis still stands up well today and is a model for much of the thinking in this area.

In chemistry, a phase-transfer catalyst or PTC is a catalyst that facilitates the migration of a reactant from one phase into another phase where reaction occurs. Phase-transfer catalysis is a special form of heterogeneous reactants are often soluble in an aqueous phase but insoluble in an organic phase in the absence of the phase-transfer catalyst.

The phase transfer catalyst (PTC) may be dissolved in either of the two phases depending on its solubility. In phase transfer catalytic reactions a shuttling mechanisms is known to operate []. The shuttling mechanism implies that if one inserts in the two phases two electrodes capable of sensing ions, one should observe oscillations of.
