Visible-light-catalyzed decarboxylation of aryl acetic acids for the construction of aromatic aldehydes

We have developed a novel strategy for the synthesis of aromatic aldehyde compounds through a visible-light-catalyzed decarboxylation oxidation reaction under mild conditions. Notably, the current protocol tolerates a variety of functional groups, and the aromatic aldehyde products are easily derivatized to other valuable functional building blocks.
