Application

Reagent used to prepare β-lactams from β-amino acids via carboxyl activation and cyclodehydration. Also used to convert α-aminonitriles into 4-chloroimidazoles.
Reagent 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
