heterocyclic derivative contain triazole ring was synthesized and characterized the product and their structures by infrared spectroscopy, 1H-NMR, 13C-NMR and instrumental techniques. Compound (4) was synthesized by reacting of Schiff base (3) with an three moles of alkyl halide (p-phenyl phenacyl bromide). Final product played an important role in photostabilizer of polymer (PS), and showed the activity as a photostabilizer when exposed to UV light (300 hours).

In recent years, heterogeneous catalysts have led to environment friendly transformations with better yields and reusability. Pd, one of the initial metals employed in heterogeneous organic synthesis, suffered from limitations like its high cost. This justifies the need for development of catalysts with abundant, low‐cost metals has been receiving a lot of attention in the scientific community. In this work, bimetallic oxide catalyst, CeO2‐ZrO2 is synthesized by a sol‐gel route. The structure and morphology of the catalyst is investigated using XRD, SEM, EDAX, TGA, BET, and TPD. It is utilized for obtaining quinoxaline derivatives at room temperature. 2,3‐Diphenylquinoxaline is obtained via a simple condensation reaction between 1,2‐Diaminobenzene and 1,2‐diketones, catalyzed by CeO2(50)‐ZrO2(50) with 87% yield in 15 min. Quinoxalines are known for their biological and therapeutic activities; hence, they are essential molecules. The biological activity of the synthesized quinoxaline derivatives has been evaluated against bacterial and fungal strains.This article is protected by copyright. All rights reserved.

“…Fe(CO) 5 , Fe 2 (CO) 9 and Fe 3 (CO) 12 are the most common ZVI complexes having significant catalytic potential. [22][23][24][25][26][27][28][29][30][31] Here, we wish to report the Fe 3 Se 2 (CO) 9 cluster in combination with Cu(OAc) 2 as an excellent catalyst for the C-N coupling reaction (Scheme 1). This bimetallic catalytic methodology is highly economical, and works under aerobic conditions.…”
