SPhos Pd G2 ChemBeads

The ChemBeads product of SPhos Pd G2, a second generation (G2) precatalyst in which phenethylamine based backbone of the (G1) complex is substituted with a biphenyl-based ligand. This improvement on the previous generation allows creating the active palladium species at room temperature with weak phosphate or carbonate bases. The catalyst proves remarkably adept at achieving a variety of Suzuki-Miyaura couplings among other cross-coupling reactions.s. Loaded on glass beads for use in high-throughput expermentation (HTE).

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.

Application in Suzuki-Miyaura coupling:


Self-arylation of 1-alkyl-3-bromo-2-phenyl-2,1-borazaronaphthalenes to form 2,1-borazaronaphthols.


Suzuki–Miyaura coupling of β-borylated porphyrins with 2-iodoaniline.


Suzuki-Miyaura cross-coupling of unprotected, nitrogen-rich heterocycles.


The cyanomethylation of (hetero)aryl halides or triflates as a tandem reaction for the synthesis of DNA-encoded libraries.[4] (37677078)

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 753009
