Abstract. 5-Imino-l, 2, 4-dithiazolidin-3-ones 1 and ones 8, 10, and-5-thiones 7. Thermolyses of thiadia--3-thiones 3 react with phenylisocyanate to afford zolidines 5 and 10 afford further 1, 2, 4-thiadiazo-5-imino-l, 2, 4-thiadiazolidin-3-ones 6. In comparison lidines 9, 11. Compounds 8-11 are available also by isomeric 3-thiono-l, 2, 4-thiadiazolidin-5-ones 2, 5, reaction of substituted guanidines with chlorocarand-5-thiones 4 yield 3-imino-l, 2, 4- ...
