Abstract

Photoacids are molecules that become more acidic upon the absorption of light. This short review highlights recent advances in the use of photoacids as catalysts for organic synthesis. Photoacid-catalyzed­ transformations discussed herein include: Protonation, glycosylation, acetalization, and arylation reactions.
