N-methyl-N-(4-nitrophenyl)thiobenzamide (4) via a mechanism involving formation of a Pd-bound tetrahedralintermediate (TI). The rateconstant for decomposition of the complex formed between 1, methoxide, and 4 is 9.3 s(-1) at 25 °C; this reaction produces methyl thiobenzoate and N-methyl-4-nitroaniline. The ratio of the second-order rateconstant for the catalyzed reaction, given as k(cat)/K(d), relative to
