ABSTRACT Two novel Cr (III) and Ru salen complexes based on {3,4‐Bis‐[(5‐chloro‐2‐hydroxy‐benzylidene)‐amino]‐phenyl}‐phenyl‐methanone ligand (CSAB) were synthesized. The characterized using various spectral analytical methods. catalytic performance of the CSAB was investigated via a four‐component condensation reaction involving aromatic aldehydes, rhodamine, morpholine, 5‐aminotetrazole under mild, environmentally friendly conditions. Different Lewis acids, bases, ionic liquid catalysts, solvents, catalyst amounts assessed to optimize parameters. Both systems demonstrated robust activity strictly managed conditions, with heterogeneous CSAB‐Ru showing superior efficacy compared homogeneous CSAB‐Cr catalyst. study confirmed capabilities both evaluated their recyclability reusability. (CSAB‐Ru) could be reused seven times, whereas (CSAB‐Cr) recycled four times. strong selectivity, resulting in high product yields. provides insights into synthetic applications complexes, highlighting potential organic transformations. It emphasizes ease use, safety, stability, component availability, quick yields, making them promising for future industrial applications.

Cu-Catalyzed Oxidative C(sp²)–H Cycloetherification of o-Alkenyl Arenols for the Preparation of Fused Furans

The Journal of Organic Chemistry, Journal Year: 2023, Volume and Issue: 89(1), P. 34 - 43

Published: Dec. 11, 2023

A practically efficient, copper-catalyzed approach for the synthesis of functionally embellished indeno-naphthofurans is developed from 1-(1H-inden-3-yl)naphthalen-2-ols. This intramolecular cycloetherification proceeds via C(sp2)–H oxygenation (C–H bond breaking and C–O forming), which enables atom-economical poly fused furans in high yields with large substrate diversity open air.
