General description
The ChemBeads[][] product of the Biaryl Buchwald ligand RockPhos. RockPhos is a bulky ligand[] that has been used in:
- Pd-catalyzed intermolecular bond formation using both secondary and primary alcohols.[][]
- The chloroethoxylation of aromatic and heteroaromatic chlorides.[]
- The three-component coupling of alkynes, alkenyl bromides and pinacolborane for the synthesis of allylic boronate esters.[]
- Loaded at 5% wt. on glass beads for use in high-throughput expermentation (HTE).
Application
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. For general uses, product is also available in powdered form (791016 )
