in Wiley InterScience (www.interscience.wiley.com).A series of 5-arylidene derivatives 3a-k, as potential antifungal agents, were synthesized in good to high yields by the reaction of 2-benzimidazolylimino-4-thiazolidinone and corresponding aromatic aldehyde in a buffered medium. These compounds were evaluated for their antifungal activities against four agricultural fungi, Botrytis elliptica, Fusarium graminearum, Phytophthora nicotianae, and Rhizoctonia solani. Thereby, it was found that the compound 1 exhibits an antifungal effect against P. nicotianae and B. elliptica, comparable with carbendazim as a standard antifungal. Our results may provide some guidance for development of some novel benzimidazole-based antifungal lead structures.

In this study, SO 3 H@zeolite-Y was synthesized by the reaction of chlorosulfonic acid with zeolite-NaY under solvent-free conditions, which was then supported by Fe 3 O 4 nanoparticles to give SO 3 H@zeolite-Y (Fe 3 O 4 /SO 3 H@zeolite-Y) magnetic nanoparticles. Several techniques were used to evaluate the physical and chemical characterizations of the zeolitic nanostructures. Fe 3 O 4 -loaded sulfonated zeolite was applied as a novel multi-functional zeolite catalyst for the synthesis of imidazole and perimidine derivatives. This efficient methodology has some advantages such as good to excellent yield, high purity of products, reusability of nanocatalyst, simple reaction conditions, environmental friendliness and an economical chemical procedure from the viewpoint of green chemistry.
