Abstract

The C=O groups in positions 4 of the molecules of 2-thioxo-1, 3-thiazan-4-one and 1,3-thiazane-2,4-dione do not possess ketonic properties. When 2-thioxo-1,3-thiazan-4-one is treated with hydrazine or its derivatives, hydrazinolysis takes place. When these substances react with P2S5, the C=O groups are replaced by C=S groups. The compounds formed possess thioketonic properties, which makes it possible to obtain derivatives of 4-imino-1,3-thiazane. The condensation of β-chloropropionic acid with thiourea leads to 1,3-thiazane-2,4-dione and the previously unreported 2-imino-1,3-thiazan-4-one. The UV spectra of the substances synthesized are described.
