Application of polydopamine sulfamic acid-functionalized magnetic Fe3O4 nanoparticles (Fe3O4@PDA-SO3H) as heterogeneous and recyclable nanocatalyst for formylation of alcohols and amines under solvent‐free conditions

Abstract

Enhancement of ethyl formate using structurally varied amines and alcohols in the presence of a catalytic proportion of sulfonic acid supported on polydopamine (PDA)-encapsulated Fe3O4 nanoparticles as a heterogeneous, recyclable and greatly efficient catalyst provided the corresponding N-formyl compounds in good to excellent yields whilst under solvent-free conditions. The magnetically catalytic system was recovered, avoiding time consuming filtration operation, via an external magnetic tool. This procedure also increases the purity of the product and promises economic and ecological advantages. Additionally, this recovery and reuse was achieved five times without noticeably decreasing the catalytic behavior.
