The reaction of w-keto amides with Lawesson's reagent (LR: 2,4-bis(4-methoxyphenyl)-l,3,2,4-dithiadiphosphetane 2,4-disulfide) is described. Treatment of 3-keto amides (2-acylacetamides) I with LR gave the corresponding 3-keto thioamides 2, along with 1,2-dithiole-3-thiones 3. Treatment of 4-keto an
