Descrizione

Descrizione generale

The ChemBeads product of tBuXPhos [2-Di-tert-butylphosphino-2′,4′,6′-triisopropylbiphenyl] is an air-stable, electron-rich biaryl phosphine ligand developed by the Buchwald group to enhance the reactivity of palladium catalysis during cross-coupling reactions. Loaded on glass beads for use in high-throughput expermentation (HTE).

Applicazioni

tBuXPhos has been used as a ligand in many C-N and C-O bond forming reactions, as well many others including:
- The palladium-catalyzed Tsuji-Trost substitution and cross-coupling of benzylic fluorides.
- The palladium-catalyzed C-N cross-coupling of sulfinamides and aryl halides.
- The protoboration of alkynes.
- ArF-alkynyl coupling with fluorinated aryls.
- The Ni & Ni/Pd reductive coupling of lignan-derived aromatics to biobased platicizers.
- The palladium-catalyzed fluorination of cyclic vinyl triflates.
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 (638080)
