    • In the present reaction, the presence of base entirely suppressed the formation of byproducts 10 and 11 possibly formed by the action of acid HX (X, OCOCF3 or Cl, Tables 3 and 4, If this means that the acid (HX) generated during the reaction is completely captured by base, the XPdOOH species could not be formed by η2-peroxoPd(II) species and HX for such an argument, see ref 25
