Application

Catalyst for C-C and C-N coupling reaction.
Pd(dppf)Cl2 may be used as an effective palladium catalyst in the following reactions:
  • Cross-coupling of sec-alkyl and n-alkyl Grignard reagents with high yield and selectivity.
  • Suzuki coupling of aryl boronic esters with [11C]methyl iodide to form functionalized [11C]toluene derivatives.
  • Kumada cross-coupling of 1,3,5-tribromobenzene with Grignard reagents to form star-shaped oligothiophenes.

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.
