Features and Benefits

This versatile polymer-bound base has been used as a reusable basic catalyst foe regioselective acylations; as both a base for the deprotonation of phenols and as a scavenger of excess phenil in the synthesis of aryl ethers from phenols; in the addition of dialkyl phosphites to a variety of carbonyl compounds, as well as, serving as a catalyst in the nitroaldol (Henry) reaction; and as a scavenger of activated ester electophiles.
