| titleOfInvention | Process for the preparation of substituted methylenedithiolanes |
| abstract | Methylene-2-dithiolanes 1,3 from alkene monothiocarbonates and thioamides. G5-. Have the C atom of the CH2 group outside the ring substituted by a hydrocarbon group. They are suitable as sulphurising agents and intermediates in the synthesis of heterocyclic cpds. with 2 S atoms. They are prepared, pref. at 100 - 250 degrees C, particularly 130 - 180 degrees C (150 - 170 degrees C). Pref. monothiocarbonates are derived from a mono-olefin (such as ethylene, propylene or a C4-8 ethylenic hydrocarbon) the chain of which also contains aryl or cycloalkyl groups. Pref. thioamides are alkyl or aryl thioacetamides, the latter being optionally substituted with C1-12 alkyl groups, Cl or Br atoms. In an example, 0.2 moles phenylthioacetamide and 0.2 moles ethylene monothiocarbonate are heated for 1 hr. at 160 degrees C. Benzylidene-2-dithiolane-1,3 is obtained in 67% yield. |
