Abstract
Various acid-promoted reactions gave the desired products in high yields by passing a solution of reactants through a reaction column packed with polystyrene-bound super Brønsted acid (1) just once. Polar and nonpolar organic solvent-swellable 1 is much superior to Nafion® SAC-13 (2) as a Brønsted acid-loaded resin packed in the column.
Key words
