“…In this work, we have developed a methodology to carry out the substitution of allylic alcohols with different ortho-, meta-and para-substituted anilines by using a recyclable metal-free catalyst, being possible to scale it up to 10 mmol (Scheme 1c). reported metal-free heterogeneous catalysts include carbocatalysts (graphene-type materials) 46,47 and supported organocatalysts, either on organic (covalent organic frameworks) 48 or inorganic (silica-based materials) 49,50 supports. As far as we know, all the heterogeneous organocatalysts found in the literature depend upon a support.…”

Carbon-based-materials, owing to their wide availability and low cost, have been utilized for a variety of applications including heterogeneous catalysis. Various carbonaceous materials have been used as supports for transition metals or other materials. These support materials have shown their potential for development of green and sustainable approaches to heterogeneous catalysis. In this review, we discuss the utilization of carbon-based materials as supports for heterogeneous catalysts, especially in organic transformations. We have focused our discussions predominantly on four categories of carbonaceous supports, namely graphene (including, graphene oxide (GO) and reduced graphene oxide (RGO)), graphitic carbon nitride (GCN), carbon nanotubes (CNT) and activated carbon (AC) for various organic transformation reactions. Several approaches for the synthesis of these materials along with their application as heterogeneous catalysts for organic transformation reactions have been elaborated in detail. In addition, different aspects of organic synthesis, including hydrogenation, oxidation, reduction, condensation, and multi-component reactions, catalyzed by these materials have been discussed. Furthermore, organic transformations leading to the sustainable synthesis of valuable products from biomass have also been discussed. Finally, after a brief summary, the future perspectives of this very interesting class of materials are provided. Figure 1. Different types of carbon-support-based materials used as heterogeneous catalysts for organic transformations.

“…In addition, such catalysts also showed better reactivity, selectivity and superior stability when compared to the other supported and unsupported counterparts . In this regards, carbon materials, such as graphene, have been considered as an interesting support due to their large surface area, thermal and chemical stability, and active cites . The combination of nanocarbon materials and heterogeneous catalytic systems is an important key to the significant activity and reusability of the catalysts.…”

A novel magnetic SrFeGO nanocatalyst (NC) was synthesized through a simple sol-gel technique by introducing strontium and iron oxide nanoparticles onto graphene. The synthesized NC was characterized using FT-IR and FE-SEM. Subsequently, the catalytic activity of SrFeGO was tested in a reaction between β-dicarbonyl compounds and aniline derivatives to gain β-enamino ketone derivatives under solvent-free conditions. It was found that SrFeGO NC is a potential catalyst for the synthesis of β-enamino ketones. The β-enamino ketone produced by such reactions could be isolated in high purity without the need for chromatographic purifications. The newly prepared magnetic graphene oxide nanocomposite could be recovered and reused for numerous times with no significant decrease in efficiency. Moreover, the protocol has the advantages of excellent yielding (up to 98%) in short a reaction time, benefitting an easy workup procedure and being environmentally friendly.

Recent advances in organic reactions catalyzed by graphene oxide and sulfonated graphene as heterogeneous nanocatalysts: a review

Abstract: Over the past decade, the application of carbocatalyst systems has been preferred over that of homogeneous catalytic systems because of their advantages such as physical and thermal stability of the catalysts in successive reaction runs and reusability.
