(A) Dependence of the initial rate on the square root of Pd(OAc)2 concentration in the presence of large excess of pyridine. Conditions: [pyridine] = 120 mM, [amide] = 100 mM, 4.0 ml of toluene, initial pO2 = 700 torr, 80 °C. (B) Dependence of the initial rate on the concentration of Pd(OAc)2 in the presence of excess pyridine and acetic acid. Conditions: [pyridine] = 120 mM, [AcOH] = 5 mM, [amide] = 100 mM, 4.0 ml of toluene, initial pO2 = 700 torr, 80 °C.
