Abstract
This paper describes an improved procedure for the preparation of crosslinked PS resins containing phenylboronic acid residues, and novel applications of this polymeric reagent for the separation of mixtures of isomers and the selective functionalization of triols. A detailed description of experiments and discussions of results obtained is presented under headings: washing of the resins; bromination of crosslinked PS; lithiation of crosslinked PS; preparation of polystyrylboronic acid resin; applications of polystyrylboronic acid resin (coupling of the polyol to the resin, benzoylation or tritylation of the remaining hydroxyls, cleavage of the product from the resin); and separation of diol mixtures.
