Synthesis of 1,2,4-Triazole Derivatives via 1,3-Benzothiazole-2,5-Diamine Supported on Nanocellulose as Novel Recyclable Nano Catalyst

The study aimed to design a novel nanocatalyst, 1,3-Benzothiazole-2,5-diamine supported on nanocellulose (BTDA@CNC), which was characterized using various analytical techniques such as FT-IR, XRD, TGA, SEM, TEM, and CHN. The nanocatalyst was utilized for the synthesis of 1,2,4-triazole derivatives through a simple and efficient three-component reaction between aldehyde derivatives, semicarbazide, and ethanol. The protocol offered advantages such as a simple procedure, high yields, short reaction time, and an environmentally benign method. The nanocatalyst could be readily separated by filter and reused without significant loss of its catalytic efficiency. The synthesized compounds showed moderate activity against both Gram-positive and Gram-negative bacteria, and the antifungal properties of the candida albicans synthesized derivatives were also investigated.
