In this study, we present a new approach to synthesizing a magnetically separable Pd‐Fe3O4@GO catalyst using a simple single‐pot method. The catalyst was employed in Sonogashira coupling reactions, demonstrating excellent results. The catalyst was studied using a various characterization method, including X‐ray photoelectron spectroscopy (XPS), scanning electron microscope–energy‐dispersive X‐ray spectroscopy (SEM‐EDS) mapping, TEM, X‐ray diffraction (XRD), FTIR, and inductively coupled plasma mass spectrometry (ICP‐MS). Pd‐Fe3O4@GO exhibited superior catalytic activity compared with its conventional counterparts in phenylacetylene‐iodobenzene coupling reactions under copper co‐catalyzed‐free and ligand‐free conditions, with a higher turnover frequency (TOF) of 118.3 h−1. Optimized conditions yielded high yields for various substrates, including inactive aryl chloride and bromide substrates, emphasizing its versatility. Also, a reaction mechanism was proposed and a kinetic model was developed. The catalyst's green chemistry potential was highlighted because of its high efficiency, purity of products, recoverability, and ease of preparation. Moreover, Pd‐Fe3O4@GO demonstrated impressive stability through multiple recycling rounds without loss of functionality, making it a promising tool for sustainable chemical processes.

Several per-O-acetyl and per-O-benzoyl glycosylthiocarbamides were synthesized by the interaction of glycosylisothiocyanates and o-phenylenediamine. While these thiocarbamideson further reactions with anisaldehyde give respective benzylidene derivatives. The identities of these newly synthesized compounds were established on the basis of usual chemical transformations, IR, ¹H NMR, 13C NMR and Mass spectral studies. All the synthesized compounds have been evaluated for their antibacterial and antifungal activity against different bacteria and fungi by the agar diffusion method. [ABSTRACT FROM AUTHOR]
