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
