摘要：

Treatment of di- and tetrabromo-1,3-dithiole-2-ones 7 and 8 with Et(4)NI yields unsubstituted diene 4, trapped as its dimer or a cycloadduct; and dibromodiene 9. Treatment of 8 with DBU gives tribromodiene 10. Spectroscopic evidence indicates that tetramethylene-TTFs are formed by heating 9 and 10 with P(OEt)(3). Diels Alder adducts are formed by 9.
