在这份报告中，我们证明了6-溴-2-萘酚的可见光光活化促进了光酸催化羰基与醇的缩醛化。我们还表明，2-萘酚时，耦合到光敏剂提供从缺电子醛缩醛。此外，测定了6-溴-2-萘酚在水中的S1激发态pKa，并显示出相对于2-萘酚具有增加的激发态酸度。
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.
