| Research Abstract |
Several new systems of macrocyclic conjugated compounds have been synthesized and their properties were examined.
1. Decyanofulvenes
The compounds of ]I[ whowed the tropicity, reflecting that the polar structures ]Ia[ contribute as resonance hybrid.
2. Bisdehydromethanoannulenes
The compounds ]II[ showed the high conformational and thermal stability. The ]34[annulene of ]II[ showed diatropicity and the ]28[annulene showed paratropicity.
3. Methanothiaannulenes
The thia]17[annulene showed diatropicity, and the thia]19[annulene showed paratropicity. Both of the thia]15[annulene and thia]21[annulene proved to be atropic.
