چکیده مقاله:

Design and use of environmentally friendly catalysts with outstanding features such as high activity, high surface-to-volume ratio, excellent selectivity, high durability, low cost of preparation and good recycling is an urgent need [1]. One of the major environmental challenges that scientists have been focusing on is the development of a broad range of selective, cost-effective and efficient recyclable catalyst systems such as magnetic nanocatalysts and functionalized nanocatalysts, and their application in a wide range of organic and industrial transformation [2-3]. In recent decades, due to the development of catalytic chemical technology, organocatalysts have attracted much attention[4]. In this study, SOR3RH-functionalized magnetic graphene oxide was used as a metal-free bronstedsolid acid catalyst for the catalysis of N-formylation condensation of various amines for greensynthesis of formamides (Scheme 1). This catalyst showed excellent performance with high yieldsfor various amines up to 95% in 2-8 h at 50 PoPC. The advantages of this heterogeneous catalyst canbe easy to use, easy recovery, high recyclability, low amount catalyst and bifunctional role of thecatalyst.
