Under catalyst-free and additive-free conditions, a novel, convenient, eco-friendly method for the synthesis of benzothiazolethiones has been developed. The three-component reaction of o-iodoanilines and K2S with DMSO proceeded smoothly and the corresponding benzothiazolethiones were obtained with good isolated yields. Meanwhile, this method could be used for the synthesis of thioureas from primary diamines. Furthermore, mechanism research showed that DMSO not only functioned as a carbon source, but also as a mild oxidant in this reaction.

A convenient method has been developed for the preparation of a variety of 1,3-benzothiazole-2(3H)-thiones. The reaction proceeds from an o-haloaniline derivative and carbon disulfide in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene at 80-140 °C to g
