Alginic acid aerogel: a heterogeneous Brønsted acid promoter for the direct Mannich reaction†
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.
