As a new reagent for the thiation of amides, the easily accessible 2,4-bis(4-methyIphenylthio)-1,3,22',41'-dithiadiphosphetane-2,4-dithione (9) shows a remarkable selectivity. This selectivitythe preferred thiation of N,N-disubstituted amidesis complementary to the one of the well known Lawesson rea
