Abstract

The preparation of several N-monosubstituted trichlorothioacetamides by thionation of the corresponding acetamides, with the use of Heimgartner's reagent is described. In contrast to the corresponding amides which undergo base-induced β-elimination of chloroform, the title compounds undergo an unexpected rearrangement to thiooxamides. The reaction mechanism is discussed.
