Kinetic studies on the ligand‐decelerated catalytic OsO 4 dihydroxylation of seven substituted styrenes with trimethylamine‐ N ‐oxide in the absence and in the presence of pyridine ligand have been carried out. The rates correlate with the Hammett relationship and V‐shaped plots with a maximum are in agreement with the oxidation of osmate(VI) ester in the rate‐determining step.
