Surfactant Derived From Stearoyl Chloride and Benzimidazole for Micellar‐Promoted Synthesis of N ‐Aryl‐1,8‐dioxo‐decahydroacridines in Water at Room Temperature

In this article, a new anionic surfactant was prepared through a one‐pot reaction of stearoyl chloride and benzimidazole with aluminum chloride under reflux conditions. Its structure was confirmed by 1 H and 13 C Nuclear magnetic resonance (NMR) analysis and Fourier transform infrared spectroscopy. The efficacy of the synthesized surfactant system was evaluated in the synthesis of 1,8‐dioxodecahydroacridines through a three‐component reaction involving aniline, 5,5‐dimethylcyclohexan‐1,3‐dione, and aromatic aldehydes. It was demonstrated that with a 0.2 g amount of synthesized surfactant 1,3‐distearoyl‐1H‐benzo[d]imidazolium chloride (DSBimCl), reaction rates could be significantly increased, and the yield in water as solvent without any co‐catalyst reached 96%. Additionally, the method is ecofriendly, minimizing the use of harmful organic solvents and facilitating efficient catalytic processes that are not achievable with traditional organic solvents.
