N, N'-alkylidene bisamides show promise in biological and pharmaceutical uses. Advanced chemistry now explores cleaner and more environmentally friendly methods. One such method involves using concentrated solar radiation (CSR) to facilitate the green synthesis of N, N'-alkylidene bisamides. This approach simplifies the process by combining aldehydes and amides in a one-pot reaction. Its solvent-free nature sets it apart, aligning with environmentally friendly practices. Any regular catalyst aids the response, making it efficient. The simplicity continues with an easy filtration step to isolate the products. Notably, there's no need for column chromatography, making the purification process straightforward. In general, a mixture of aldehyde, aryl/alkylamide was taken in a round bottom flask. The reaction mass in RBF was then kept under the concentrated solar radiation (CSR) setup with continuous stirring on a magnetic stirrer. After few hours of stirring the precipitate was observed. After completion of the reaction, the precipitated product was washed with water and recrystallized from hot ethanol to afford pure product symmetrical N, N'-alkylidene bisamide. Dimethyl sulfoxide (DMSO) was used as a solvent to prepare a stock of derivatives. Luria Bertani broth (LB) used for the present study viz; Staphylococ-cus aureus MCC 2408, Escherichia coli MCC 2412, Pseudomonas aeruginosa MCC 2080 and Klebsiella pneumoniae MCC 2451 used to evaluate the antibacterial property of the derivatives. Indeed, this method offers an eco-friendly solution and showcases the potential of using renewable energy sources in chemical synthesis. It is a significant step towards sustainable practices in chemistry, particularly in producing complex organic compounds for biological and pharmaceutical purposes.
