Wipf, Peter; Jenny, Christjohannes; Heimgartner, Heinz (1987). 2,4-Bis(4-methylphenylthio)-1,3,2lambda5,4lambda5-dithiadiphosphetan-2,4-dithion: Ein neues Reagens zur Schwefelung von N,N-disubstituierten Amiden. Helvetica Chimica Acta, 70:1001-1011.
As a new reagent for the thiation of amides, the easily accessible 2,4-bis(4-methyIphenylthio) -1,3,2lambda5, 4lambda5-dithiadiphosphetane-2,4-dithione (9) shows a remarkable selectivity. This selectivity - the preferred thiation of N,N-disubstituted amides - is complementary to the one of the well known Lawesson reagent. Thiation of diamides of type 2 with 9 leads via cyclization of the corresponding dithiodiamides directly to 1,3-thiazoIe-5(4H)-thiones 1 (Scheme 3 )
