The use of environmentally benign nanoreactors in water is crucial for sustainable organic synthesis. Herein, we report that nanomicelles formulated by two surfactants (cationic cetylpyridinium chloride (CPC) and nonionic polyoxyethylene (23) lauryl ether (Brij-35)) in water produce efficient catalysis of diperiodatoargentate(III) directed oxidation of unsaturated alcohol, isoprenol. Interestingly, the maximum speed of reaction was observed when CPC and Brij-35 existed together in a 1 : 1 mole ratio. The kinetic outcome was elucidated with the help of ¹H NMR analysis and favourable micellization of the binary surfactant system. The various mixed micellar microenvironment influences the reaction rate following the confinement of reactants at close proximity to the micellar pseudophase. The reaction, performed through this green envelope of mixed micellar media, reduces the time of reaction effectively.

一种有前途的混合胶束方法，用于调节水性介质中双高碘酸 (III) 对异戊二烯醇的氧化

在水中使用环境友好的纳米反应器对于可持续有机合成至关重要。在此，我们报道了由两种表面活性剂（阳离子氯化十六烷基吡啶 (CPC) 和非离子聚氧乙烯 (23) 月桂基醚 (Brij-35)）在水中配制的纳米胶束可有效催化不饱和醇异戊二烯醇的双过碘酸 ( III ) 定向氧化。有趣的是，当 CPC 和 Brij-35 以 1:1 的摩尔比共存时，观察到最大反应速度。^在1的帮助下阐明了动力学结果二元表面活性剂体系的 H NMR 分析和有利的胶束化。各种混合胶束微环境会影响反应物在靠近胶束假相处的限制后的反应速率。通过这种混合胶束介质的绿色包膜进行的反应有效地缩短了反应时间。
