Aryldiazonium Salts to Azo Dyes: Diazo Coupling01:11

Aryldiazonium Salts to Azo Dyes: Diazo Coupling

3.8K
The reaction of weakly electrophilic aryldiazonium (also called arenediazonium) salts with highly activated aromatic compounds leads to the formation of products with an —N=N— link, called an azo linkage. This reaction, presented in Figure 1, is known as diazo coupling and occurs without the loss of the nitrogen atoms of the aryldiazonium salt. Highly activated aromatic compounds such as phenols or arylamines favor the diazo coupling reaction. The coupling generally occurs at the para...

Area of Science:

  • Crystallography and Materials Science
  • Supramolecular Chemistry

Background:

  • Polymorphism is a critical phenomenon in crystal engineering, influencing material properties.
  • Understanding crystal packing and intermolecular interactions is key to controlling solid-state forms.

Purpose of the Study:

  • To characterize a newly identified triclinic polymorph of a specific sulfonylurea compound.
  • To elucidate the structural differences and intermolecular interactions responsible for crystal dimorphism.

Main Methods:

  • Single-crystal X-ray diffraction analysis to determine the crystal structure.
  • Analysis of dihedral angles, hydrogen bonding, and aromatic π-π stacking interactions.
  • Comparison with a previously reported polymorph to identify key differences.

Main Results:

  • The second triclinic polymorph (C13H16N10O5S) was characterized, featuring two molecules (A and B) in the asymmetric unit.
  • Distinct dihedral angles between ring systems were observed for molecules A and B.
  • Intramolecular hydrogen bonds and extensive intermolecular interactions, including N-H⋯N, N-H⋯O, C-H⋯O, C-H⋯N bonds, and aromatic π-π stacking, form a 3D architecture.

Conclusions:

  • The observed dimorphism is attributed to differences in molecular conformations and crystal packing.
  • Variations in intermolecular interactions, especially aromatic π-π stacking, are crucial for the distinct polymorphic forms.
  • This research contributes to the understanding of crystal engineering principles for sulfonylurea derivatives.
