Abstract

Oxidation of phenols by benzeneseleninic acid 2 in methylene dichloride leads to the para- quinones, whereas oxidation by benzeneseleninic anhydride 1 is confirmed to afford the corresponding ortho-quinones. Addition of indole, as a phenylselenium (II) trapping agent, inhibits the formation of phenylselenoquinones in the oxidation with 1 or 2.
