Application of Cu(Hdmg)₂ as a simple and cost‐effective catalyst for the convenient one‐pot reductive acetylation of aromatic nitro compounds

Abstract

In this article, we have developed a novel and simple one‐pot reductive acetylation of aromatic nitro compounds with sodium borohydride (NaBH4) in ethyl acetate (EtOAc) under reflux conditions in the presence of the bis(dimethylglyoximato)copper(II) complex [Cu(Hdmg)2] as an efficient and cost‐effective copper‐containing catalyst. Notably, using the above‐mentioned one‐pot reaction, the corresponding acetamide derivatives were obtained in high to excellent yields.

Catalytic Application of Tactically Aligned Cd(II)‐Based Luminescent 3D‐Supramolecular Networks

“…The similar state of the art materials and others such as nanoparticles, composites and doped materials were compared with 1 for the sake of the progress of the reported procedure (Table 6). [40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57] By careful reading of the table, one can easily identify the reduction of nitro to amine utilized drastic conditions such as synthesis of the catalyst, use of noble metals or expansive metals, harsh H-source such as explosive H 2 or NaBH 4 , hydrazine hydrate, silanes, formats etc. and time of the reaction for the catalysts/amine formation.…”

“…However, in the present work we focus on synthetic strategy and selectivity towards CR of 1 with other reported adsorbents. Beheshti et al [36] and Mohammad et al [59] have reported synthesis of the Cd-based coordination polymers and Cd-MOFs respectively for dye adsorption, but it involves tedious synthesis procedure. Thus, 1 has an advantage of facile synthesis conditions and selective towards CR.…”

“…All these interactions make CR a potential candidate for strong adsorption towards 1. [25,36] The following equations were used to calculate the adsorption efficiency and the quantity:…”

“…[34] Recently, the strategic syntheses of Cd (II)-CPs have gained much consideration because of their non-linear optical properties and structural diversity and architectural flexibility [35] also due to the fact that very few reports on Cd (II) based CPs/MOFs have been reported for adsorption and separation of dye molecules. [36]…”

Two different facile and efficient approaches for the synthesis of various N-arylacetamides via N-acetylation of arylamines and straightforward one-pot reductive acetylation of nitroarenes promoted by recyclable CuFe2O4 nanoparticles in water

“…In continuation of our research programs on various type of organic reactions [67][68][69][70][71], especially on the simple methodologies for the preparation of N-arylacetamides [72][73][74][75], we wish to report two different facile and efficient approaches for the synthesis of divers N-arylacetamides via N-acetylation of arylamines and straightforward one-pot reductive acetylation of nitroarenes promoted by recyclable CuFe 2 O 4 MNPs in water at reflux (Scheme 1).…”
