Abstract

Aryl bromides (4 equiv) were coupled efficiently with organotin (1 equiv) in an atom-efficient way using the tetra (triphenylphosphine) palladium/polyethylene glycol 400 (Pd (PPh3) 4/PEG 400) catalytic system in the presence of sodium acetate (NaOAc) as base at 100° C, providing excellent yields of the corresponding functionalized biaryls in short reaction times.
