Photoacid-catalyzed acetalization of carbonyls with alcohols?
Organic & Biomolecular Chemistry Pub Date: 2022-07-15 DOI: 10.1039/D2OB00435F
Abstract
In this report, we demonstrate that visible light photoactivation of 6-bromo-2-naphthol facilitates the photoacid-catalyzed acetalization of carbonyls with alcohols. We also demonstrate that 2-naphthol when coupled to a photosensitizer provides acetals from electron-deficient aldehydes. In addition, the S1 excited state pKa for 6-bromo-2-naphthol in water was determined and shown to have increased excited-state acidity relative to 2-naphthol.
