Dаtum izdаvаnjа: | 1-јан-2004 | Čаsоpis: | Journal of the Serbian Chemical Society | Sažetak: | The potential of directional non-bonded 1,5-type S⋯O interactions to initiate the incipient stage of an in situ rearrangement of N-unsubstituted thiazolidine enaminones to functionalized 1,2-dithioles has been demonstrated. The spectral characteristics, as well as X-ray structural analysis of a selected rearranged product, indicate that a dynamic interconversion occurs in solution between the 1,2-dithiole and the 3,3aλ4,4-trithia-1- azapentalene bicylic form. The lack of the rearrangement in the case of a N-methyl substituted enaminone precursor is attributed to an unfavorable methyl migration in the last reaction step. | URI: | https://open.uns.ac.rs/handle/123456789/11435 | ISSN: | 03525139 | DOI: | 10.2298/JSC0411909M |
