Abstract

A systematic study on the use of liposoluble PEG5000Bu3N+ Br-(1a) as the catalyst in a series of anion-promoted reactions carried out under both liquid-liquid (LL) and solid-liquid (SL) phase-transfer catalysis (PTC) conditions is reported. A comparison of the catalytic efficiency of 1a and that of popular soluble nonsupported and/or insoluble resin-supported onium salts 1b-i is also included. Classical nucleophilic substitution reactions, ie, Br-I ...
