1,2,4-trithioles 2a-e are readily obtained in good yields by dimerization of benzoyldithioacetic acid derivatives using samarium diiodide as a promotor under very mild conditions. The structures of compounds 2a-e were determined by IR, 1 H, and 13 C NMR spectroscopies using heteronuclear multiple bo
