AbstractA simple and efficient method for the synthesis of one-pot, three-component thioacetamides via Willgerodt–Kindler reaction was developed using a sulfated polyborate catalyst. The method described the reaction of ketones, sulfur, and secondary amines with high yields under a solvent-free condition at 100 °C. The key advantages of the present method are short reaction time, high yields, solvent-free
摘要通过使用硫酸化的多硼酸盐催化剂,开发了一种通过Willgerodt-Kindler反应合成一锅三组分硫代乙酰胺的简单有效的方法。该方法描述了酮,硫和仲胺在无溶剂条件下于100°C下高产率的反应。本方法的关键优点是反应时间短,产率高,无溶剂条件和催化剂的可回收性,这带来了经济和生态上的回报。 图形概要
