A rapid, green, and efficient one-pot, three-component Kindler reaction was developed using a sulfated polyborate catalyst. The method described the reaction of aldehydes, amines/ammonium acetate, and sulfur for the synthesis of thioamides using sulfated polyborate under a solvent free condition at 100?°C. The key features of the present protocol are high yields, short reaction time, easy workup, and recyclability of a catalyst which gives economical as well as ecological rewards. The present method also has an ability to tolerate a variety of functional groups. Graphical abstract: [Figure not available: see fulltext.].
