Abstract
An efficient and convenient procedure for the preparation of 2-amino-(1,4)-benzoquinone-4-phenylimides from anilines using a λ5-iodane-1-hydroxy-1,2-benziodoxol-3(1H)-one-1-oxide (IBX) oxidation in dimethyl sulfoxide is described. This protocol offers a general approach to compounds consisting of an iminoquinone moiety with a wide range of functional groups. A single electron transfer (SET) process was postulated to explain the oxidation pathway.
Key words
IBX - iminoquinone - aniline - SET - oxidation
