    • The cross-coupling of 3-nitroiodobenzene afforded better yield of the desired biphenyl than that of 2- or 4-substituted iodobenzene probably due to the deiodination from the latter one, which is highly active. The cross-coupling of 4-cyanoiodobenzene at 50 °C gave the corresponding biphenyl in 80% yield, indicating almost no difference in the reactivity arisen from the substitution pattern. The slightly higher reactivity of 4-methoxyiodobenzene over 2- or 4-substituted one would be attributed to the poorer electron density at the 1-position that facilitates the oxidation addition to the palladium metal
