(Chloromethylene)dimethyliminium chloride Usage And Synthesis
Chemical PropertiesPale brown to yellowish-brown crystalline powder
UsesReagent or Reactant for the synthesis of:
  • β-Lactams vis the Staudinger reaction
  • N-vinyl substituted indoles via cross coupling of NH-indoles with vinyl bromides
  • Multi ring-fused 2-pyridone-based fluorescent scaffold
  • ester prodrugs as anti-poxvirus agents
  • Trimethine cyanine dyes for sensing G-quadruplex formation
  • Phospha-isosteres via Hundsdiecker-Barton iododecacarboxylation
  • 2-Azetidinones via [2+2]-cycloaddition

Used for studying organic photosensitizers for application in dye-sensitized solar cells
Uses(Chloromethylene)dimethylammonium chloride is used in the synthesis of beta-lactams, n-vinyl substituted indoles and fused 2-pyridone rings and 2-azetidinones. It is used as a formylating agent and used in the preparation of anti-poxvirus agents. It is used in Staudinger reaction and Hundsdiecker-barton iododecarboxylation reaction. It is widely used for studying organic photosensitizers, which finds application in dye-sensitized solar cells.
