Among the vast scope of phase-transfer catalysis (PTC) applications, the largest sector involves the reaction of anions that are reacted and/or generated under PTC conditions with species containing electrophilic centers. Among the most widespread an

It is only within the last two decades that heterogeneous enantioselective syntheses involving chiral phase-transfer catalysts (quaternary ammonium and phosphonium salts, macrocyclic miltidentate ligands, polypeptides, polymer-bound quaternary salts

In previous chapters we learned that a phase-transfer catalyst must have two particular chemical functions to be successful, that is, it must rapidly transfer one of the reactant species into the normal phase of the other reactant, and second it must

Phase-transfer catalysis (PTC) is an excellent technique both in liquid—liquid and liquid—solid (and sometimes in liquid—vapor) modes for conducting displacement reactions with anions.

Critical to the success of phase-transfer catalytic (PTC) processes are (1) the maximization of the rate of transfer of reactant anions from the aqueous or solid phase to the organic phase, (2) the maximization of the rate of transfer of product anio

An important problem facing the designer of industrial phase-transfer catalysis (PTC) processes using soluble PTC catalysts concerns the removal of the catalyst from the reaction mixture, and its economic recycle, as noted in Chapter 4. This problem
