应用

  • Ligand used in a synthesis of heterocycles by palladium-catalyzed C-N cross coupling of 3-bromothiophenes with 2-aminopyridines. Also used in a ruthenium-catalyzed alkylation of active methylene compounds with alcohols.
  • Metal chelating ligand for catalysis.
  • ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.
