The effect of the substituents X in complexes of the (XC/sub 6/H/sub 4/Cl)Cr(CO)/sub 3/ type on the rate of nucleophilic substitution of the chlorine atom by the action of sodium methoxide in methanol at 40-70/degree/C corresponds to the series p-OCH/sub 3/ < 0-CH/sub 3/ < p-CH/sub 3/ < m-CH/sub 3/ < H < m-OCH/sub 3/ < p-Cl < o-Cl < m-CO/sub 2/CH/sub 3/ < m-Cl < p-CO/sub 2/CH/sub 3/ and is described in the case of meta and para substituents by the correlation equation log k/sub 70/degree/C/ = 3.56/sigma/ - 3.95. It was concluded that the nature of the effect of substituents on the rate of aromatic nucleophilic substitution in the arene complexes of transition metals depends on the charge of the intermediate.
