One electron oxidation of 4-methyl thiophenol

Abstract

4-Methyl thiophenol(MTP) undergoes one electron oxidation with N{sub 3}{sup .} and Br{sub 2}{sup -.} radicals at pH 11 to give 4-methyl phenylthiyl radical (CH{sub 3}C{sub 6}H{sub 4}S{sup .}) with {lambda}{sub max} at 310 and 500 nm. OH radicals react with MTP by addition to the benzene ring and also by oxidation to give both hydroxycyclohexadienyl type radicals ({approx} 25%, {lambda}{sub max} = 390 nm) and CH{sub 3}C{sub 6}H{sub 4}S{sup .} radicals ({approx} 75%). In acidic solutions, H-atoms, CO{sub 2}{sup -.} and (CH{sub 3}){sub 2}COH radicals abstract H-atom from -SH group to give the same species, thus acting as oxidants. This radical was found to be neither oxidising nor reducing in nature and decayed by second order kinetics. (author). 2 refs., 2 figs.
