The central aim of this investigation was to innovate a novel nanocatalyst for the eco-friendly synthesis of
benzothiazoles through an acceptorless dehydrogenative coupling of 2-aminothiophenol and benzyl
alcohol, mitigating environmental impact. In pursuit of this objective, we immobilized a poly-sulfonamide
(PS) onto the surface of a layered double oxide/sodium alginate composite (LDO@SiO2-Pr-SA), exhibiting
exceptional activity and selectivity. A noteworthy achievement was the unprecedented immobilization of
Fe species on this innovative nanocomposite, comprising LDO, sodium alginate, and polysulfonamides,
further enhancing the environmental sustainability and economic efficiency of the process. Additionally,
the catalyst demonstrated cost-effectiveness, safety, scalability, and reusability (up to 6 times), as
confirmed by hot-filtration tests establishing its heterogeneity. The synthesis yielded impeccable results
with high efficiency and reduced reaction time, marking a significant advancement in green and
sustainable catalysis
