General description

(tBuXPhos)Pd(p-TMSCH2CH2CO2C6H4)(Br) 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.

The utilization of isolated Palladium Oxidative Addition Complexes (OACs) has had a significant impact on Pd-catalyzed and Pd-mediated cross-coupling reactions. Despite their importance, widespread utility of OACs has been limited by the instability of their precursor complexes. Herein, we report
