The 3,5-diamino-1,2,4\_dithiazolium salts DADTX [X = Cl dHrO), Br, I, ClO,, Nor, fSO,(H,O)] have been prepared and their i.r. spectra investigated in relation to that of dithiobiuret and to the molecular structure of the thiouret hydrohalides. In the DADTX salts the dithiobiuret v(NH& and 6(NHz) ban
## Abstract Reaction of the 3,5‐diaryl‐1,2‐dithiolium salts 2 with the metal cyclopentadienides 4 and 9 leads to the formation of the tricyclic compounds 6 and 10 via a ring‐opened intermediate, which undergoes an intramolecular Diels‐Alder cyclization. Compounds 6 and 10 rearrange by treatment wit
