Effects of organic solvents on other phase-transfer catalytic reactions

5 Effects of organic solvents on other phase-transfer catalytic reactions 

Not only will the organic solvent influence the NPTC reaction, but it also affects the character of NPTC. Another type of transfer mechanism takes place when the 

Data obtained from Harris et al. C4-PEGI5OO-C4 represents a PEG of MW 1500, capped by a butyl group at both ends 

In principle, formation of a third catalyst could be accomplished either by (1) use of a phase-transfer catalyst that has limited solubility in both the organic and aqueous phase, or (2) by use of a special solvent, perhaps a fluorocarbon, having great affinity for the catalyst but only modest affinity for both of the reactants. T etra-n-butyl-ammonium salts frequently form third layer when used in conjunction with an organic phase that has little polarity (e.g., neat 1-chlorooctane, toluene, or cyclohexane as solvent, but only dichloromethane) and with a concentrated aqueous solution of inorganic salts.
