Abstract:
Using (vinyl tosyloxy)benziodolium salts, we divergently synthesized a series of conjugated diene derivatives with the Mizoroki-Heck reaction. Subsequent coupling reactions of these dienes provide access to polycyclic aromatic conjugated diene derivatives. Derivatization of ester-substituted conjugated dienes enabled the synthesis of ortho-iodoarylpyranones. Further oxidation of ortho-iodoarylpyranones furnishes cyclic arylidonium salts, which serve as versatile reagents for polycyclic aromatic hydrocarbons.

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable,...
