摘要:
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 umdergo base-induced beta-elimination of chloroform, the title compounds undergo an unexpected rearrangement to thiooxamides. The reaction mechanism is discussed. (C) 1998 Elsevier Science Ltd. All rights reserved.
