(E,E)-2,5-Bis(5-chloro-2-methoxyphenyl)-3,4-diazahexa-2,4-diene
Abstract:
The title compound, C(18)H(18)Cl(2)N(2)O(2), was synthesized by the reaction of 1-(5-chloro-2-methoxy-phen-yl)ethanone with hydrazine hydrate. The mol-ecule lies on a crystallographic twofold axis passing through the mid-point of the N-N bond with one half-mol-ecule in the asymmetric unit. The dihedral angle between the two aromatic rings is 44.33 (4)°. In the crystal, inter-molecular C-H⋯O inter-actions link the mol-ecules into columns along the c axis.

E2 Reaction: Stereochemistry and Regiochemistry
When a substrate with two different β hydrogens undergoes an E2 elimination, the presence of a strong base can yield two regioisomeric alkenes. The more-substituted alkene is the major product and...

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...
