WebSynthesis of the vinyl sulfone and chloroethyl sulfone derivatives of poly (ethylene glycol) (PEG) is described. The chloroethyl sulfone (CES-PEG) is rapidly converted to the vinyl sulfone (VS-PEG) in the presence of base but is stable in water at neutral pH. Reactions with small molecules such as beta-mercaptoethanol and N alpha-acetyllysine ... Webpoly (arylene ether sulfone)s, which are potential candidates for PEM, are prepared via nucleophilic aromatic substitution and post- sulfonation. Chlorosulfonic acid was used as the sulfonating agent and chlorotrimethylsilane is also used as a protecting agent against cleavage of the isopropylidene group.
