Application

tBuBrettPhos Pd G6 TES is a G6 Buchwald precatalyst. The G6 precatalysts are air-stable, palladium-based oxidative addition complexes (OACs) that offer an alternative to the previously developed classes of palladacycle precatalysts. Unlike previous generations, the bulkiest biarylphosphine ligand precatalysts are readily prepared. These precatalysts have been shown to be effective for many reactions, including C-N, C-O, and C-F cross couplings.

In this report, we describe the application of palladium-based oxidative addition complexes (OACs) as effective precatalysts for C-N, C-O, and C-F cross-coupling reactions with a variety of (hetero)arenes. These complexes offer a convenient alternative to previously developed classes of precatalysts

Buchwald G6 Precatalysts: Oxidative Addition Complexes

Buchwald G6 precatalysts are oxidative addition complexes that are thermally, air, and moisture stable. The catalyst activation doesn’t require a base and generates innocuous byproducts.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
