reaction of 4-nitrophenolate ion with the 4-nitrophenyl ester is slightly imbalanced whereby bond formation does not keep up with bond fission in the transition states; the transitionstate, therefore, has some phosphorylium ion character. Transfer of the diethylphosphoryl groupbetween weakly basic oxyanion nucleophiles is probably a concerted process with a transitionstate with more of the character
