Yokoyama, Masataka published the artcileSynthesis of heterocycles using a new immonium salt derived from N,N-dimethylthiourea, Computed Properties of 6972-05-0, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1982), 1059-62, database is CAplus.
Treatment of Me2NCSNH2 with NaH, CS2 and MeI in THF gave Me2NC(SMe):N+MeCS2Me I– (I), which underwent cyclocondensation reactions with nucleophiles to give heterocycles including triazolines, an oxadiazole, a thiazole, a triazine, a benzoxadiazepine and a benzothiadiazepine. E.g., I was refluxed in EtOH with N2H4 for 4 h to give 74% triazolinethione II. Similar treatment of I with HSCH2CO2Et-LiN(CHMe2)2 in THF at -70° for 1 h and at room temperature for 1 h gave 47% thiazole III.
