Description
Summary:The development of robust and cheap photocatalyst systems for visible-light induced organic substrate transformations is a significant uprising research topic at the crossroads of green chemistry and modern synthetic methodology. Atom economy, efficiency and selectivity are key parameters for the future practical applicability of the specific processes catalyzed. In this context, we report a simple and sustainable oxygen-dependent route for oxidizing various aromatic and aliphatic aldehydes to the corresponding carboxylic acids at room temperature under visible light and sunlight irradiation mediated by cobalt phthalocyanine tetrasulfonic acid (CoPcS) supported on reduced graphene oxide (RGO). Remarkably, products are obtained with (81-100)% conversion and 100% selectivity.
