Opis

Opis ogólny

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).

Zastosowanie

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
