Abstract

The compound MeRe(S)(mtp)(PPh3), 2, where mtpH2 is 2-(mercaptomethyl)thiophenol, was used to catalyze the reaction between pyridine N-oxides, PyO, and triphenylphosphine. The rate law is -d[PyO]/dt = kc′[2]·[PyO]1/2, with kc′ at 25.0 °C in benzene = 0.68 (4-picoline N-oxide) and 3.5 x 10-3 dm3/2 mol-1/2 S-1 (4-NO2-pyridine N-oxide). A chain mechanism with three steady-state thiorhenium species as chain carriers is implicated.
