N-aryl amides hold significant importance in organic chemistry due to their widespread presence pharmaceuticals, agrochemicals, and various bioactive compounds. As a result, catalysts preparation methodologies for amide derivatives have long been target of active investigation interest. In the current work, simple accessible route was adopted magnetic catalyst [Fe3O4@SiO2-DHB/DI(S-NH)-Pd (0)] then its catalysis three-component synthesis via carbonylation reaction between aryl iodides amines examined. experiments, efficiency producing range with high yields short under mild conditions unequivocally confirmed, confirmed through experiments. High desired compound ease separation, reusability catalysts, conditions, accommodation substrates, thorough analysis determination produced compounds characterization purification taken as key features this work.

Abstract Over the past decade, metal‐oxide nanoparticles have attracted scientific community due to their extensive use in medicinal and pharmaceutical industries. In addition, metal‐based made extraordinary development as a catalyst construction of diversely functionalized heterocycles. There is surge applications nano metal oxides mild, inexpensive, efficient, green, reusable, heterogeneous for various organic transformations. Among numerous oxide nanoparticles, zirconia‐based catalysts find wide construct diverse range heterocycles using multicomponent reactions. The current article selectively reviews nano‐ZrO 2 useful one‐pot green synthesis variety heterocyclic scaffolds reported from 2011 onward. This review divided into five sections: i) five‐membered with one heteroatom, ii) two heteroatoms, iii) three/four iv) six‐membered heterocycles, v) tandem

Abstract We present a novel, efficient, eco‐friendly sonochemical strategy for the synthesis of fused nitrogen heterocycles via Brønsted acid‐promoted, one‐pot multicomponent reactions (MCRs). This method involves rapid assembly 6‐aminoindazole, aryl aldehydes, and 1,3‐cyclodione derivatives (barbituric acid, dimedone, 1,3‐dimethyl barbituric acid) under mild identical reaction conditions. The approach delivers diverse range highly functionalized heterocyclic frameworks, including 11‐phenyl‐1,6,7,11‐tetrahydro‐8 H ‐pyrazolo[3,4‐ f ]pyrimido[4,5‐ b ]quinoline‐8,10(9 )‐dione, 8,8‐dimethyl‐11‐phenyl‐1,6,7,8,9,11‐hexahydro‐10 ]acridin‐10‐one, 7,9‐diphenyl‐1,6,7,9‐tetrahydro‐2′ ‐spiro[pyrazolo[3,4‐ ]quinoline‐8,5′‐pyrimidine]‐2′,4′,6′(1′ ,3′ )‐trione derivatives. molecular structures these compounds were unambiguously confirmed through 1H‐NMR, 13C‐NMR single‐crystal X‐ray diffraction (SC‐XRD) analysis. Additionally, control experiments provided valuable mechanistic insights into pathway. protocol stands out its efficiency, high yields, broad functional group tolerance, making it versatile tool diversity‐oriented in modern chemistry.
