Dimethyl 2,2'-[ethane-1,2-diylbis(sulfanedi-yl)]dibenzoate
Abstract:
The title compound, C(18)H(18)O(4)S(2), was synthesized by the reaction of 1,2-dibromo-ethane with methyl thio-salicylate. The complete molecule is generated by crystallographic twofold symmetry: two methyl benzoate units are linked by an -S-(CH(2))(2)-S- bridging chain with a gauche S-CH(2)-CH(2)-S torsion angle [72.88 (16)°]. The two aromatic rings form a dihedral angle of 79.99 (6)°. In the crystal, adjacent mol-ecules are linked into a three-dimensional network by non-classical C-H⋯O hydrogen bonds.

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.

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...
