AbstractThe palladium-catalyzed arylation of rac-(E)-3-acetoxy-1,3-diphenylprop-1-ene with arylboronic acids was studied under controlled microwave irradiation conditions. Avariety of different catalysts, bases, and solvents were explored in order to achieve optimum yields in the shortest possible reaction times. The best isolated yields were obtained using Pd2(dba)3$CHCl3/PPh3 as the catalytic system, potassium phosphate monohydrate as the base, and toluene/H2O as a solvent system. Microwave irradiation using 5 mol% of the palladium catalyst for 90 s (max. temp 170 C) generally afforded the cross-coup領(lǐng) products in good to excellent yields.
