An effective and new approach is proposed for the synthesis of regioselective 3H-1,2,4-dithiazol-3-imines through S[sbnd]S and C[sbnd]N bond formation for the first time from benzothioamides and isothiocyanates under transition-metal-free conditions. This protocol proceeds by using hypervalent iodine(III) compound of phenyliodine diacetate (PhI(OAc)2) having additive cesium carbonate in acetonitrile solution at room temperature to provide facile access to 3H-1,2,4-dithiazol-3-imine derivatives from readily available starting materials with broad substrate scope, insensitive to air and moisture, regioselectivity and affluent up to gram scale.

1,4-Diaryl-1,3-diaza-1,3-butadienes containing mobile chlorine atoms at positions 2,4 were synthesized.The previously unknown N-thioaryl-N'-arylthioureas were used as the starting materials.It was shown that mild oxidation of the latter by chlorine gives
