Abstract

We demonstrate that highly dispersed alginic acid aerogel beads can function as heterogeneous promoters for Brønsted acid catalyzed reactions. The activity displayed by alginic acid, benchmarked in the three-component direct Mannich reaction, depended on its morphology, with the aerogel formulation providing distinct advantages over other forms.
