Dual Substituent Effects on Anilinolysis of Bis(aryl) Chlorothiophosphates

)are positive for both electron-donating and electron-withdrawing Y substituents. The kinetic results of 1 arecompared with those of Y-aryl phenyl chlorothiophosphates (2). The cross-interaction between Y and Y, dueto additional substituent Y, is significant enough to result in the change of the sign of ρ
