Beschreibung

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Greener Chemistry. ChemBeads are advanced solid-coated beads for high-throughput experimentation in various chemical applications. They enable precise dispensing of solid reagents, allowing researchers to conduct reactions with minimal material use, thus supporting waste prevention and catalysis principles while ensuring accuracy and reproducibility. This technology enhances efficiency and streamlines experimental processes in chemistry. Click here for more information.

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).

Application

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.[1]
- The protoboration of alkynes.[2]
- ArF-alkynyl coupling with fluorinated aryls.[3]
- The Ni & Ni/Pd reductive coupling of lignan-derived aromatics to biobased platicizers.[4]
- The palladium-catalyzed fluorination of cyclic vinyl triflates.[5]
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)
