General description

The AdBrettPhos ligand coated of glass beads. AdBrettPhos is a phosphine-based ligand used in the direct monoarylation of ammonia and suppresses diarylation. In addition, it is a good ligand for five-membered heteroarene couplings and is employed in the preparation of phosphine-ligated palladium complexes to facilitate C-N coupling reactions. For use in high-throughput expermentation (HTE).

Application

AdBrettPhos has been used in:
C-N Coupling reactions. (see 31896889)
The fluorination of alrl triflates.(see 25346547)
The Palladium-Catalyzed C-O Cross-Coupling of Primary Alcohols. (see 29474078)
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 (768154)

The structure of the stable Pd(0) precatalyst [(1,5-cyclooctadiene)(L•Pd)2] (L = AdBrettPhos) for the Pd-catalyzed fluorination of aryl triflates has been further studied by solid state NMR and X-ray cystrallography of the analogous N-phenylmaleimide complex. The reactivity of this complex with
