摘要

简介:即使在更高的温度下,维尔斯梅尔·哈克(VH)反应也大多太慢。然而,即使在中等温度下,在胶束介质中也观察到快速而容易的转化。材料和方法:使用不同类型的表面活性剂(阴离子十二烷基硫酸钠、阳离子十六烷基三甲基溴化铵和非离子-TX-100)作为胶束形成化合物。结果和讨论:胶束介导的反应表现出显著的速率加速和最终产物产率的提高。VH反应追求伪一阶和二阶动力学。结论:本研究首次证明了甲酰化和乙酰化衍生物的合成及其动力学行为的可行性、可控性、无毒性和简便性。

A Kinetic and Synthetic Approach of Surfactants Accelerated by Vilsmeier- Haack Acetylation and Formylation with Anisole
Introduction: Vilsmeier-Haack (VH) reactions are mostly too slow even at higher temperatures. However, quick and easy transformation was observed in micellar media even at moderate temperatures. Materials and Methods: Different types of surfactants (anionic – sodium dodecyl sulfate, cationic – cetyltrimethyl ammonium bromide, and non-ionic – T X-100) are used as micelle forming compounds. Results and Discussion: Micellar-mediated reactions exhibited dramatic rate accelerations and improvements in the yield of end products. The VH reactions pursued pseudo-first- and second-order kinetics. Conclusion: This study with anisole is the first such report demonstrating a feasible, controllable, non-toxic, and easy methodology for the synthesis of formylated and acetylated derivatives and a study of their kinetic behavior.
