Protocol for the preparation of primary amine-containing catalysts on the resin.

Abstract

In light of escalating sustainability concerns, addressing catalyst usage and waste production challenges becomes crucial. Here, we introduce a robust protocol for crafting recyclable polystyrene-supported primary amines, providing a promising solution via heterogeneous catalysis. The protocol details immobilization onto insoluble resins through ester, ether, or amide bonds, facilitating the synthesis of heterogeneous catalysts with diverse organic components. For complete details on the use and execution of this protocol, please refer to Kanger et al.¹.
