Abstract The reactions of methyl (or ethyl) isothiocyanate with dianions (4, 5, and 6), which are readily derived from available cyclic thioureas (1, 2, and 3) with butyllithium, gave ring fused 1,3-disubstituted 1,3,5-triazine-2,4(1H,3H)-dithiones (7) and/or thiocarbamoyl derivative (8) as major products.
